Problem Keeping A/C Charged on GMC Jimmy?

[Rachel M]

I don't have any gauges or anything like that, but since my a/c was blowing warm air all summer, I bought a recharge kit with the hose already on it and filled up my vehicle. That lasted about a month. Now what?

your a/c system has a leak in it....you can get a can of freon with leak finder (dye) ..put it in your system and it will turn the dye color where it is leaking...probably red...or you could take it in and have a tech look at it..but you know what that will mean....$$$$$$$$$$

Most likely the O ring on your compressor has gone bad and is leaking from there. The is the most common area where the leak will be coming from. What ever you do, DO NOT BY A STOP LEAK for your A/ system. They create more issues from a messing up the expansion valves and orifice tubes.

Your going to have to bring your Jimmy in and have them repair the affected area where the leak is coming from. You might get lucky by inspecting your A/C system and find the leak your self. If you see any area's around where the a/c lines connect or the compressor area that has oil, that would indicate where the leak is. At worst, your condenser or evaporator may have a pin hole and will need to be repaired or replaced.

Sorry for the bad news and please keep us posted.
