Re: Cooling fan problem
FAN relay?
The sensor goes to the Computer (SMEC) and then sends a signal to the fan relay. The A/c relay is separate, and has a different relay (high speed, like you thought). The relays, and the wiring to them is usually where I've found the trouble. Some Van's also have a second sensor, on the radiator, and it too, will cause the fan to stop working.
if you're not sure, spend $25.00 at alldatadiy.com and get the schematics for the Van online. the cooling fan circuit is drawn out for you very simply, and it's not that hard to work on, really!
good luck,
