a c problems Sign In

1998 dodge Durango 5.9 engine with about 180,00 miles
last year I juiced up my a c and didn't have any problems with it, about 2 weeks ago I turned it on just to check it, it worked ok .
today I turned it on because its hot out and it was blowing warm air, im not sure if the compressor is kicking on or not, I checked all the fuses and they seem ok,
anyone help me ? thanks, Dennis from Wisconsin

If you can't tell if the compressor is on or not, then this repair is certainly not for you. You need to find a competent AC specialist.

Dennis - have to agree here. If you can't tell if a compressor is engaged or not don't touch anything to do with it. Blasting in refrigerant sounds like what you did that wild luck just happened to work once before also shows you shouldn't mess with this without some homework on just how a system works.


Just FYI, when compressor isn't engaged everything to do with A/C except a pulley is just going along for the ride. When engaged you have to know a lot or ruin a good system easily,

OK - You've figured out what engaged or not is and it does "kick on" you just said. Does it stay engaged or quickly shut down?
Reading between the lines it worked you said with a juice up job a couple weeks ago so the overwhelming problem is it leaks.


You can't just "juice up" as you put it and get that right so easily but might have with whatever you used to get whatever product into the system.


IDK where to go with this until I/we know what you have for testing anything. At a minimum you need gauges and fast thermometers if it will stay engaged (I about know it doesn't) can get some info if this is a low charge problem or other.


Then to do anything about it some fixes are simple some are real difficult but end up with charging it properly with the equipment to do that.


Strongly think it's a leak to find and fix then move on to charging it up knowing how much product/refrigerant you are putting in.


Are you equipped to do that plus know when to stop if it isn't going properly?


If not there's just so much to know and have to proceed and this leak must be quite fast so can't be ignored.


Everyone wants to save a buck and this area of auto work takes a lot of understanding and equipment, doing it right or risk making it much worse and VERY costly,

Another suicide can victim.Frown

If your going to play with AC, you need an AC manifold gauge set. Tired of people coming in here providing no system pressures and using the one gauge wonder tapped into a suicide can.

Your lucky. Seen people push refrigerant into a system when it has an expansion valve issue or they overshoot and create too much head pressure. Now you need to find the leak. Every time that thing gets low the compressor isn't getting lubed properly. Eventually the compressor is going to grenade or lock up.

Yep, and it loses some more oil with every bit of leak.
