Now I remember last fall that the A/C efficiency was dwindling significantly and barely cool. The compressor was also beginning to make a rattling noise. Now that we've had a few warm days, I kick on the A/C and am reminded of this fact. So I took my '99 5.2 Durango down to Firestone. They were able to test and recharge the system but said they didn't know how long it would last as the compressor is rattling pretty good. So an hour and half later and $134 poorer, I"m asking myself is there anything I can do to fix this myself?

They didn't quote me a price on just the compressor, but on the entire A/C kit with all the parts contained and that alone was $850. Who knows what labor would be.

So, is this bearings in the compressor being shot? Can I buy some time?

Thanks fellas!

 

I'd just buy a replacement compressor.

Are they pretty simple to replace? I would think that since they're on the top, there's not much that you shouldn't be able to get to.

 

Yep, and replace the dryer. You have to drain the system with a special vacuum, replace the parts, then re add the Freon.

 

So, how does this work? I need a special vacuum? Can I rent one? How difficult is it to replace both the dryer and compressor? Is there a sticky or FAQ on this?

Obviously, I just paid $134 to have Firestone refill the system. Am I going to lose all that when it comes time to replace the compressor and drier? The very loud rattling sound reminds me of bad bearings.
I'm going to guess and say that these compressors are not serviceable? That is to say that you cannot simply top it off with fresh oil like you would do your engine?
Also, I'm seeing a lot of aftermarket kits that are out of Asia fairly cheap. I'm really leery of the quality of these. Should I steer clear of those and only go with OEM? I know it's going to be a lot more expensive and that means taking me longer to raise the funds. Keep in mind that I'm on disability and I'm a full time student at 60 years old.

Thanks Hydra!

 

130 bucks to refill the system with freon? I refilled my truck (from bone dry) for about 35 or so (including adding some sealant to it to try and fix the leak).

 

There's a set fee they all set for testing the system with dye to make sure there are no leaks. That's partially why the procedure takes almost 90 minutes.

 

Buy your own parts and take it to an independent a/c shop. You should be able to get better rates there. I just had my a/c lines replaced, system vacuumed and filled for $100. Of course the lines were another $100.

Or go old school. Loosen a line, put a rag over it and walk away for an hour. Swap your pump then go get it charged up.
But of course I didn't tell you to do that and dont be telling people you did that. Throw the rag in the trash.
Besides, R134A isn't as bad as R12. Lol

 

I know not these things of which you speak!
