ac not working

You could have a leak that is causing you to lose the freon you add. Tell me, do you have gauges to read low and high side pressures? That is the only way I am going to be sure what is happening. Also, let me know how much freon you added.

I used 2 12oz cans of 134a but the plastic caps sorta broke off the top if can on both of them so we just held the cap on there with the hose attached as we sprayed it in , only that half of the freon was coming out of the top of can instead of in the car Because they were broke bit we emptied both cans . Also you would think we would have gotten enough in there for it to do at least something but it did nothing

Also the freon had a sealer in it for leaks

I have to be honest, it doesn't sound like enough got in the system. The system holds 1.10 lbs of freon. If you got half of each can in, that totals 12 ounces which too little.

Do me a favor, see if a local parts store will rent you gauges so we can see what the low and high pressure reading are. It is really hard for me to know what is happening without knowing that. If you can't get one, can you tell me if the low pressure side AC steel line from the compressor is getting cold? It should and the high side will be hot.

Hang in there... I'm trying, but it's hard without all the info. Hope you understand.

Air conditioning compressor and temperature gauge stop working simultaneously. What is the connection? Problem comes and goes.

Hello,

It sounds like the PCM went out but to be sure lets run the codes to see what comes up. Here are two guides that should help us fix the problem.

Here is the air conditioner wiring diagrams so you can see how the system works.


Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.

Thanks for this post I had this problem and had to get a rebuilt PCM cost me $340.00 all set I love this site.

When your driving and stop at a light the heat blows out cold air & the heat isnt as hot anymore. Could this be the heater core going bad

check coolant level first. also check battery terminal ends for cleanliness and check belt and tensioner recommended replacement is 60,000 mi
