Hey friends, it's Len here, at 1A Auto. Today we're working on our 2001 Ford Focus ZX3 Hatchback. I want to show you something fairly simple. We're going to be removing and reinstalling a heater control unit out of the center dash. It's going to be super easy. I can do it. You can do it too. As always, if you need any parts, you can always check us out at Thanks.

Okay, so to do this, we're just going to need some basic tools. If you have an aftermarket stereo like this one, you know you're going to have to figure out how to get it out. Generally speaking, if it's the original stereo, there'll be like two holes on this side, two holes on this side. You push in the little tools, and then you should be able to slide your stereo out. This is after market. So what I like to do is just give it a little tug and then come along the side with my trim tool. Just like that. I'm going to do the same to the other side. Just go in and give it a little twist. Give this a nice, easy wiggle. There we are. I'm Being gentle. Just come in here. We'll disconnect the antenna. Set that aside. Make sure you don't forget to connect that back in. Grab this stuff right here. There we are.

Check your electrical connectors, make sure there's no corrosion. This one looks good. Do the same to this one. There we are. It looks good. We'll set our radio slash head unit aside. Okay, so we have four screws, one here, here, and then the same on the other side, there and there. I'm going to use my seven millimeter. You can use a ratchet or whatever you you've got. There's the first two bolts. They're both the exact same. All four bolts, the exact same. We'll set these aside. Move ahead to the next step.

We're going to continue with our plastic trim tool. Just come in under here along the top. Just trying to slide this out a little bit. Seems to be catching over here. I wonder what this thing is. Who smokes cigarettes nowadays? Get that out of here. Okay, so we've got all of our connectors in here. Coming down along, we've got the connector for the blower motor speed right here. We've got our selector to designate where the air is going to be coming out of, whether it's your vent or your defrost or your floor. Well, wherever you want it to come out of, obviously. And then this over here.

This is the selector, for hot and cold or AC and heat right here. So to get this to pull out a little further, I'm just going to disconnect the a four way flashers switch. Let's see if I can grab it right along the side. It's a little push connector. Okay, we'll set that aside. This gives us a little bit of room. On the backside of the selector switch there's a Phillips head screw, so I'm just going to use my quarter inch ratchet with a Phillips head bit, because it's a little easier than trying to... Maybe it's a little easier. Let's see. Trying to get a screwdriver back there is pretty hard.

There's our screw. Super short. We'll set this aside. Let's start disconnecting some of the wiring from the back here. I'm just going to grab them, give them a little tug. They pop right out. Take a peek at them. They look good. This right here, that's got a little a push on it. You just go ahead and push right there. It should separate. There we go. Okay. This one, same thing. I'm just going to press on the little tab. Roll it down, lift it up. There we go. This right here. It's hard to see from this angle, but I think I can pull it out like that. Take a peak. Looks good.

This one right here. Let's see. It should be here. Slide that out. Take a peak. It looks good. Cruising along. We've got one left here. Just going to press on the bottom. Slide that out. There's our center console facial unit. Okay, so right behind here is where our heat control unit is. It's a large unit. It's this white area. We have some Phillips head screws that hold it in. Looks like four of them. So I'm just going to take my Phillips head, remove the screws. I'm fairly certain they're all the same. Get that one out of there in a second. Set that aside. Grab this. This one could go a little bit more. There we are. Just like everything else in life, it's never easy, especially on camera. So there we are.

All right. Let's get this re-installed. On the back side here you can see where the four screws were. One, two, three, and four. I'm just going to line it up with where everything goes. Slide it in. Let's take our screws.I'm going to see if I can do this with my gloves. It's pretty doubtable. I'm going to grab a magnetic screwdriver. Okay. It's time to put it in the screws. Make sure I've got my screwdriver going the right way. If you have something that's magnetized, it's really going to come in handy at this point because trying to get way down deep in there, it's really not the easiest. Unless you're lucky enough to have something that's magnetized. All I'm doing is starting them in. Once they're all started, at that point I'll go ahead and snug them down. All four screws are started in. I'm just going to take my screw gun, because it's a little quicker. I'm only screwing into plastic, so I'm not applying very much pressure. Essentially once these bottom out, just give it a little bit after that and that's it. There we are. And grab this one. There we are. We can go ahead and install it back into the vehicle.

All right. So now we're on the backside again. We've got all this wiring mess. Let's see if we can figure it out. This one right here, it's going to go right in there. Click. I heard it. We've got this one. It can go right up in here. Click. Heard it. This one, nice and big right over there. And we've got this guy. See if I can bring it around. There it is. It goes right on those two prongs, right there. And then lastly for this lower area, we've got this right here. I'm going to start with the lower area of it. Try to get it pressed in and then squeeze up to the top. That's in there. Cool. All right.

We've got these over here. The single wire goes to the bottom. Just press it in there. There's no click really. Well, it sounded like there was a click, but usually I never hear a click. Grab this one. There we are. I heard a click. That's nice. I like it. I like it. We have this guy right up here, that goes in for the four way switch. There we are. We've got extra parts. Just kidding. We're going to make sure that we get the stereo back in, up and running on this puppy. Can't drive without a stereo. Everybody knows that. Get this in here. Just going to press it in. There we are. Very nice. We'll grab our four screws and we'll continue.

We've got our four screws. Seven millimeter and I just have it on a nut driver, but you can use whatever you've got. I'm just going to start it in, just like always. I like to get all the bolts for whatever it is I'm working with started at the same time, before I go ahead and tighten any of them down. Just in case I have to shift anything around. There we are. All four are started. Just snug these up. All four are tight. Let's move ahead to the next step.

All right. So when you're underneath the dash, you're going to notice that maybe this right here doesn't line up with what you're dealing with underneath the box. I'm going to need the box. Okay, so when you're underneath the dash, you might notice that this inner area right there doesn't line up with what you're dealing with. If it doesn't, just reach your hand up. Give it a little twist until it does line up with what you need it to. Okay? I'm going to turn it like this. I'm pretty sure I left it off on feet. I'm going to come back through. There we are. Okay. Yeah, that looks good. Now to do this, I'm just going to line it up and then press it in. I mean, there's no screws or anything to hold this. There we are. All three of them clicked right in. Easy peasy.

I'm going to come back up here. I'm going to listen. Yup. I'll show you what it's doing down under there. Can you see right straight down at the end? What it's doing is it's changing where the air's going. It's pretty basic. I probably don't have to tell you that, but I do want to show you that it is functioning. Okay, so now we're going to connect in the stereo. Okay, so we've got our stereo unit. Let's connect it in. There we are. Be careful not to let it fall and smash or anything like that. These are fairly sensitive. Put that in. This connector right here was not connected to anything when we started, so I'm not worried about connecting it now. That only leaves us one thing, the antenna wire. It just goes right into the back of your unit. Just press it in as far as it can go. Bonk, bonk. There we are. Slide this right in here. Nice and easy. If it feels like it's getting jammed up then pull it out and try again. There we are. Very nice. All right.

Lastly, this useless thing. It's good for change or whatever you want it for. Let's see if I can get it in there. There's a little channel that runs right along here. I just need to get it in there. Very nice. All right, friends. There you are. Easy peasy. Thanks.
