were is the fan relay on a 2000 vw jetta

"nancy, ""The Fan Control Relay is bolted beneath the battery tray.

That's a known failure item when the fans are inoperative.

Part number is: 141-951-253-B

The Fan Control Module is on the lower driver side of the radiator...

or it can be located on the driver side lower framerail."" This is what it looks like (just a different number :) Hope this helps, good luck."

I have changed the control module temp sensor thermostat n radaitor n still cant get my ac clutch to engage nor the fans to spin which ive checked the fuses n tested the fans im starting to think that theses jettas have bad grounds throughout there wiring harnesses cause i fixed my lisence plate light by regrounding the harness in the trunk
