OK, I've been searching and just can't seem to find the answers I need.

I have a 1987 SDL Turbo Diesel. I took it in to get the AC looked at. The mechanic tested it, found that it was 2 lbs low on R134. Put it in. Said that the AC Relay was bad. Put that in.

When you start the car, the compressor kicks on right away. I let it sit there and idle for 15-20 minutes and it works great. The minute I started driving, the compressor stopped. When I was coasting down the road, about 60 seconds later it kicked back on, but then turned off right away as I started to accelerate again. When I parked the car, it took just over 60 seconds to start again.

Is this normal. I've read where the compressor shuts down to provide more power to the engine and also so it does not lock the compressor up with the high RPM's the engine is running while accellerating. But it just seems a little strange. Can anyone help me out.
