2000 Silverado 4WD 2500 251,000 miles
Over the past 2 summers I’ve had 3 reasonably good mechanics try and fix the AC (starts out cold/cool then goes ambient temperature after no more than 10 minutes or so, the hotter the ambient temperature the less time it blows cool even if it does, this problem has been getting worse). Going from memory of things I don’t understand–a hose connection(s), switch, coolant leak check and more. The last suggestion was a new compressor. And here’s my problem. According to the mechanic there is no specific compressor test. So replacing this expensive part is largely an expensive, semi-educated guess.
- Would a shop that specifically works on AC’s have a diagnostic that could sniff out whether the compressor was the problem?
- If a mechanic does the compressor work is it ‘industry right’ that I’m on the hook for the bill even if the work didn’t solve the problem?
