It's only been about a year sence I converted my 89 300e from R12 to R134. My compressor went out about a yea ago and when I bought a new one it was for 134, so I replaced reciever dryer and the expansion valve and recharged the system with 134.
It dosn't work well in stop and go traffic but it works fine up on the highway.
anyway, today my compressor started making noises. when Iturn the A/C on the cutch on the compressor starts to engage, but then it just locks up.
Can anyone tell me what might cause this and if it can be fixed or am I going to buy another compressor again after only about 14 months.
