Subject:      87 Westy, A/C Question
Content-Type: text/plain; charset="us-ascii"

In my '87 Westy, I put a couple cans of R-134 in a couple of weeks ago. The van mostly sat for three years after being converted from R-12 to 134.

The air now blows cold, OK.

Today temps are in the low 90s and I fired it up to see if it was still blowing cold.

After a few minutes, what I think is the mid-speed radiator fan came on and stayed on.

When I shut the van off, the van ran for just a few seconds and went off.

Does this sound like the high pressure switch, or an outside air temp problem? I've heard that the A/C systems don't like to work when it's really hot out.

Back when I added the refrigerant, temps were in the 80s.

I ran the van for a LONG time and never heard the fan come on.

I do remember the mid-speed fan coming on in the past, in the R-12 days, when the temp was really hot and we were traveling at 70 mph on a hot night.

Thanks for any help.
