Question about 1993 Volkswagen Eurovan
Replaced thermostat and did noticed some grinding on the thermostat, as if it had problems opening, but it still overheats. I noticed that the fans don't come on, I used a jumper wire from batt. + to fan and both work, checked the fuse and it's good, I don't know where the relay is, what do you suggest i do next?
The relay should be located in a box on the driver sid under the dash. i would check with a different relay. i usually use the relay for the a/c clutch . if the fans kick on it was the relay if the the fans still don't come on when engine reaches temp the it would be that the temp sensor is bad.

If my memory serves me right, there are two fuses under the hood, one for each fan motor near the driver side headlight inside a small plastic box with a snap on top. Check these also. The fuses look like flat strips if metal less than an inch long held in by two screws. You can temporarily bypass them to test the motors by jumping a wire from the battery. I have had a motor seize before.

I had the same problem and it turned out to be corrosion on the terminal ground cables. I think it was throwing off the sensor somehow. Fans would not kick on until the engine became very hot. Mechanic tried various things until he took a close look at the cables and noticed significant corrosion near the starter. I bought the van from a guy who lived near the ocean and I believe the salty air boosted the corrosion.
