Hello everyone, I have a 2005 v6 f150 and the ac compressor gets no power.


I checked fuses, relays, high and low pressure switches even the ac climate control unit.

My question is: I found a relay box in the drivers side fender with a small relay and a small fuse.

Can anyone tell me what this box is or what that relay does? I read a lot of forums and some say it's the ac clutch relay.

Any input would be appreciated.


I would post pictures but I'm on my phone. Unless what I did worked and you are able to see the pic I uploaded.

 

Really ? No one ?

 

That's the auxiliary relay box. Here's the diagram from the manual:

 

Relay box for the DRLs and 4x4 system.

 

Nice "cold air intake"......

 

Thanks for the info. I guess the problems lies elsewhere, I'll keep looking for possible problems.

 

Lol thanks. It was free so why not.

 

So the clutch relay or diode are eliminated as the possible cause? I was monitoring this thread as I'm having intermittent no-AC issues, but if I had no power at the compressor, I would replace the diode first, then the relay. What am I missing?

 

low freon will kill power to the compressor too

 

Why did you guys disregard the R202 relay? It says it's for the AC clutch. Couldn't it be that?
