Good morning guys,

I am having some challenges with the ac of my 2005 Acura tl. My ac stopped blowing cold air and I was doing some troubleshooting to find out if the problem was my compressor or just a relay or fuse. After attempting to force my compressor to start manually my climate control is not coming up. I tried to follow the normally steps advised by other users such as fuse check and putting everything back to normal. Any suggestions from You will be greatly appreciate it.

 

I also tried to disconnect the battery to see if that will reset anything. But it did not work..the lights comes up but I can't turn on the ac at all...I have also a tsx but I would like to avoid switching parts and stuff like that...

 

im confused...So your climate control display DOES appear but A/C will not turn on?

If that's the case, youre most likely low on refrigerant.

 

How?

But did you check the A/C clutch relay? A failed relay is a known problem with early Acuras, all models, all years before 2010/11. Switch that relay with another relay of the same type/ kind, then try the A/C again. Or test the relay, or just replace it - the A/C relay only costs $6 unless you replace with the upgraded relay which is $30

Yes, that link is in the RDX section, and the TSB is for an MDX, but the same low quality A/C relay has been used for the past 10 years on all Honda/ Acura models, and the upgraded relay has been used on all Honda/ Acuras for the past several years.

WHile the link above, and the TSB, discuss a relay that has STUCK CLOSED, relays can also fail OPEN, meaning that the A/C clutch is never going to engage, so that the A/C compressor will never produce cold air.
