Air conditioning compressor
I know this is a really odd question this time of year. I’ve been chasing a coolant leak and I’ve noticed that my air compressor will stop and start in regular intervals. It’s a 1986 6.9. Granted it’s 38 degrees out in beautiful Harrisburg, PA, when I turn the AC on I get cold air and I had the heat cranked for some time. Is there a clutch on the compressor?

Yes, the clutch is on the front. When it is disingaged the pulley just free wheels as the belt spins it.
When it is energized you should hear it click it is engaged.
You could have some loose wiring/plug. I think if you are low on Freon it will give you the problems you
are experiencing. Iam no AC expert, just things I remember reading.
One of the big guns should come along soon...

I actually toggled back and forth from hot defrost to max AC with the fan turned up. Sorry if what I had originally posted was worded in a confusing manner

My '88 IDI van also cycles the AC when it's on anything but NORMAL VENT. So if I put it on defrost and heat, the dumb air conditioner turns on. Talk about a waste of MPG and energy, especially in cold climates. If I were the OP, I would install a shut-off switch in the cab on the pigtail to the compressor for the winter. In September, I'd open the switch, then in April, I'd flip it back on.
