The a/c on my beautiful '83 TD has recently developed an odd problem.
I can feel the compressor engage, but the fan won't begin to blow for 5 minutes, or longer, after starting the car (even in vent mode) and sometimes simply stops. I can engage the 'defrost' mode and the fan blows high and sometimes by switching quickly to a/c (or vent) I can catch the fan and get cool. Otherwise it's just wait 'til the fan decides to come on.
Monovalve looks good.
Help, the afternoons are hot in Albuquerque.
