Autozone parts guy? AC Pro? See my tag sig line. Does not sound legit at all. I would be more interested in the high side than the low side on this one. If the compressor is not actually pumping, then the low side will show high pressure (into the red full). If it is pumping and the high side is goi...

The thing about this forum is if you are patient, willing to listen and do as suggested, there are people here who are willing to help. I have come across many of the same problems I have read about here. I have gone back to old thread and found solutions to problems. If you want to keep going with ...

No one here (that I am aware of) is going to tell you to put in leak stop of any sort. The proper thing to do is find the leak, repair it, then recharge it. Because you are using 12A (basically propane), I'm going to assume you are in Canada or somewhere else where you cannot purchase 134a without a...

Any chance that the water sitting on the evaporator could cause it to rust and leak? I have replaced more evaporators this year than any other year and have been wondering this.
Thanks

WOW I had about the same idea as GM Tech, I must be learning something here!

Do you know much history on this project? Has the front ever worked the way it was when you got started working on it? The reason I ask is "maybe" the oriface tube is just not there and that is the problem. Just thinking, but maybe someone thought it was just a filter and did not put one b...

I saw this walking through a parking lot today and thought I would share it. This is personally the first time I have ever seen one, and it is even in use!!!!
