Air Conditioning problem
2003 Mitsubishi Galant 6 cyl Two Wheel Drive Automatic 90,000 miles
About a year and a half ago my car was in a 30 mph front end collision. I was hit on the corner of the passenger front quarter panel and the hood of the vehicle. The repairs were made by a less than reputable shop that was actually recommended by my insurance company.
About 6 months after the accident my ac went out. I took the car to my regular and very trustworthy mechanic who informs me the repair shop did not replace my compressor, rather they jb welded a valve back on and the weld was no longer holding and I needed a new one.
the weather got cooler and I put it off until it started getting hot again, I am in texas. A couple months ago I purchased a refurbished compressor off ebay and a new dryer at my local auto parts store and had my mechanic put them in. I am not sure about the order of steps here, but he flushed the system, installed the parts, put it under vacuum for a couple hours, and the rebuilt compressor seemed fine.
10 days later, while going down the highway, I heard aloud skreeching sound, my ac light starts blinking and the air starts blowing hot. Once I stopped I turned the car off and then started it again, the ac lasted for 2 minuted just sitting in the driveway, then I got the same noise and the ac goes out. What was happening is the clutch on the ac compressor stopped spinning, the noise was the belt continuing to spin and then the compressor would just shut off.
So I get a brand new aftermarket compressor and not wanting to take any chances this time, we replaced everything but the lines. We replaced the compressor, dryer, expansion valve (yes, you do have to take the dash OUT), condenser, and evaporator. This pos has a brand new ac system in it.
now I am having the same problem with the new compressor. Worked fine for 3 or 4 days and now after about 20 seconds I get the skreech sound and the compressor shuts off. The pressure on the low side of the system shoots up about 10-15 psi as this happens. Its like the clutch is only halfway disengaging or just spinning too slow.
the serpentine belt is new also. There are no leaks or restrictions in the system. The oil still comes out clean so there does appear to be any debris in the system either. Anyone have a suggestion as to what we should look at next?
have the same problem?
