Need to do a little troubleshooting here. Run van until fan goes to high
speed. Unplug Radiator fan switch. If fan keeps running and compressor
is cut out, than problem is with the AC. May be overcharged, back
expansion valve, receiver drier, or other blockage in system. Hope this
helps,

Dennis

Dennis,

Yup, the fan comes on at the lowest speed when the A/C is turned on.
When the outside air temp is below 80 degrees I don't have a problem
with the constant cycling on and off of the high speed fan vs. the
compressor.   With that info, would "high pressure" still be the cause
of the cycling?  I had the A/C converted to R-134 last summer.  IIRC, it
did this before I had it converted too.

I did replace the radiator temp sensor a few years back.  I wonder if
it's the wrong one?  Does anyone know the correct part number for an '88
with A/C and automatic?

TIA

Jim
