Great heater and A/C control
Our 2000 Jeep Wranglers heater and A/C control knobs had all broken off. We got this replacement and it was a snap to install! It took my husband maybe 15 minutes to finish the job. It works perfectly! Now we can heat the Jeep toasty warm in these Arctic temperatures!!! A-1 shipped quickly too.

I got the right part the 1st time. And on the day it was supposed to be there. It worked perfectly. At 1/2 price of getting one at a parts store. I couldn’t be happier. Carry on the good work.

My fan is working on high speed only. What part do I need to replace to have lower speeds?

Buy a new control module

Generally, when your fan is running on High only it is not your control unit. It is your fan control resister which is located by the fan under the dash on the right-hand side. When this item goes bad it fails to the high speed only.
G B November 29, 2018
We recommend you check the blower motor resistor first, as that is the component that controls the speed of the fan.

I had the same problem with my 2000 Wrangler. about 2 years ago. I finally got fed up with it and decided to replace the controller. I think it cost about $100 and was not too hard to replace if you have some mechanical know-how. You have to remove the dash to get to electronics. Works great now. 1AZMX00145-Jeep Wrangler Heater & A/C Control

Most likely youll need the heater controller. Some of the older Jeeps have heater controllers that run off vacuum, which is fine until theres a blockage in one of the vacuum lines. Ive replaced my 99 TJs heater controller 3 times and I have a spare waiting. For me its always the same: high is the only speed that works.
