Start simple...
Don't replace any component 'till you've replaced this!
Most mechanics (including Nissan's) don't seem to know about this; many have replaced everything else and it still hasn't worked; they won't honor their failier either, it's just "hard stools".

New life in an old car
A/C is working like new once more with this new relay. Replaced it with a new compressor and dryer. Make A/C like new. Start with all new parts.

Where is this relay located?
Shawn G on Jun 18, 2017
BEST ANSWER: It is on the backside of the fuse box , left side dash , through the compartment on the lower left corner of the whole dash assembly. You have to pull the whole fuse box assembly forward from its mounted position and turn it to the back side
Of the box, there you'll find the blue relay.
