Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I’m Ron and I can help you.
I have been in this business since 1975. I am ASE certified and an instructor. I am confident we can resolve your problem together. Please understand that I don't know your skill level. I can't see, smell, hear, or touch the vehicle, so it may take a few replies to get to satisfactory results. Be patient please!
I also try to give all of the information you may need expecting a positive rating. I will also continue assisting you after you have rated me.If there is any reason I cannot get a positive rating, please let me know why,so I can go another direction.
Either the gauge is wrong, or the compressor is locked up. That reading is impossible for the compressor being off or on. Hope this helps you. Check for power and ground to the compressor also.
I forgot to mention that when the system is OFF, the pressures should read the same at both ports. The low side would never read that high except for what I mentioned earlier.
Thanks again, Ron
