The A/C in my '87 300SDL has been wirking fine, even at 100F today.
This eveining after the outside temp had dropped to 85F, the nice cool
breeze from the climate control system suddenly turned very hot. I'm
guessing that this is the primary symptom of a faulty mono valve???
The car was converted to R134a by the PO, so I've been concerned that
the system might blow up with the black goo at any time, but then
again, this is the second summer since I bought it.
So, do I just order the mono valve repair kit, or do the trouble
shooting routine?
TIA,
While it MIGHT be the monovalve, you really do need to do the
diagnostics. Was the compressor still running when the things got warm?
If the compressor stopped running then it's MOST likely a problem with
the KLIMA/serp belt saving circuitry. There are other prossibilities too.
