I know there are alot of topics about this, but I havnt been able to find one for the 2005 TB EXT.

My fiance had been using her a/c for a while now this spring. All of a sudden one day, it was only cold if we were driving (and still not really cold), then the next day is was blowing warm air... Yesterday I looked at the compressor, and it was not spinning.. So today I checked the pressure (yes one of the auto part store kits), and it was reading 5psi. So I put in one can of refrigerant. It raised the pressure to 25psi (probablly between 70-75 degreed outside).. I decided to get another can. .Drove to the store, checked it before I bought the can, and it was at 35psi, so I figured Id leave it... Once I started to put in the first can of refrigerant, the compressor kicked on and off twice, then stayed on steadilly. the air was a little cooler, but not much, and if you werent moving, it was warm..... Any ideas as to what could be wrong.. could I just need an evac & charge?

Thanks for all the help in advance, and sorry for the one millionth a/c topic.. Just couldnt find an answer for an 05 tb

**EDIT*** NOt sure if this helps, but when I feel the condensor (i think... the silver canister next to the coolant res.) it is warm... I always thought it should be cold when the a/c is running

A/C issues

Welcome to TrailVoy! Please fill out your Profile on your TV so everyone has a better idea about that. Oh that silver looking thing is sometimes called accumulator .If the A/C is running : the Compressor Clutch is working ;the accumulator should be cold .

All filled out now.. Thanks...


With the A/C running, the compessor clutch is spinning.. The "accumulator", never got cold, it was actually quite warm, but by the time I felt it, it was closer to 80 degrees outside, so that could be where the heat was from, but it was by no means cold.

Nice job on the profile.

Well if you had been loosing pressure then probable leaking.You'll need to have a shop use a sniffing tool to sort out to start or they also use a dye with ulta-violet lamp.Hope this Helps.

Thread moved.:cool:

If you had no pressure in the system, it leaked out somewhere. You will need to have the leak found and repaired. Every one I have ever seen has been a failed seal in the compressor, so don't be surprised if they want to replace the compressor.
