Hey guys.
I haven't been on here in about a year or so.
Here is my problem:
I have a 1987 2.9L Ranger with the original HR980 compressor and 161,000 miles. The truck's nearly perfect because I bought it 3 years ago from the original owner, who is now 80 years old.
The A/C's R-12 eventually leaked down, so I converted it to R134-A. After about a year, it eventually screwed something up. Seems the compressor isn't separating the high and low pressures internally. I have high pressure on both the high pressure and low pressure sides. The compressor gets extremely hot very quickly and no cold air at all at the vents.
I can blow air through the whole system (including the compressor). I have replaced the drier and the expansion valve drawn a vacuum and refilled the system with R134-A and the correct amount of that gas' compatable oil.
Anyway, I am looking for help from anyone experienced with the HR980 compressors, conversions, alternatives, kits, etc.
I found some new HR980s on ebay, but they all had the spring-lock connection points, while mine has the screw-on fittings.
Anyone ever replaced their HR980 with something else (hopefully reasonably priced)? Any suggestions what I can do to get some A/C in my truck?
I'm at my truck's mercy. It's upper 90s and 90-95% humidity here in SC everyday right now.
Thanks.
