Hey everybody having some weird issues with my A/C and need some advice. Ok so it all started when just outta no where my a/c stop blowing out cold air, so I thought to myself I'm probably gonna need a recharge so I went ahead and did that along with a leak check and still no change, I then checked the compressor to make sure the clutch was coming engaged and that checked good, next step I checked relays and fuses all good and lastly I replace the hvac controls inside the car but I'm still not getting cold air in the cabin and at a loss if you guys can direct me in the right path I'd greatly appreciate it

 

so, adding refrigerant could have exacerbated your problem... there are MANY different things that can cause an A/C system to not blow cold...

you need to start with taking everything out and putting back in exactly what needs to be in there...

then we can try and go from there

 

i agree there can be several things wrong, some simple some complex. We need some more information regarding as to what you did prior to the a/c not blowing cold.

honestly, the best thing to do for a/c (as I'm not experienced with a/c repair by any means) is to have a professional check it out. Or if you do have experience, I'm sure you've probably checked for leaks correct? Are you sure you're at the correct amount of freon? Too much or too little can cause malfunction.

 

use a vacuum gauge to check if theres a leak

 

Ok so how the problem started was just one day to the next it stopped blowing cold air but was working perfectly fine the day prior. No other work was done to the vehicle prior to the issue happening . As for the servicing it was done by a professional with a leak check after it was cleaned out and serviced.

 

One thing I did notice today I connected the pressure gauges to the low side and noticed that when I turned on the a/c the pressure didn't move or change so correct me if I'm wrong isn't it suppose to drop and go back up on the initial turn on the a/c
