I'm trying to find the fuse for the radiator fan motors on a 1999 chevy venture

radiator fan may not be coming on make sure you can hear it running. Fan motor or relay is probably bad

Well that can be true but you can't be sure without running some tests.
Did you get the cap off ? Is the radiator full of coolant ?
Was the radiator fan running when it was showing hot on the gauge ?

Hi My cooling fan not working

Try checking the fan fuses an relays and go ahead and change ur thermostat might be faulty with the extra heat from the motor

Okay, First you go and check the RADIO fuse in the underside of the hood. If the Fuse is blown then you have to replace it. If its not then to reset the power door , you have to take out the fuse for 30 sec. then replace and start vehicle then try to open it. Good luck, with them chevy ventures. we had one and we had to replace radiator and Head for $1200 and new window motors twice and switches.

No more fuses,General Motors had alot fo problems with power window motors I personally have replaced hundreds of these in all there models over the years.Sometimes if you tap on the motor with the door panel off while depressing the switch the motor will move again for a while but it will need to be replaced. Just make sure you have switching voltage and ground at the motor connector with the switch depressed.Good luck

located in thermostat housing or in intake nearby (where top hose connects from radiator to engine)

sounds like u might have a blown head gasket is your oil milky colored
