You may have a short in the temp wire itself..........I would do a continuity check on that wire and clean ground......Hope this helps.

2004 Pontiac Grand AM Cooling motors wont work.


Can you jumper the relay to make the fans run ? The computer sends a ground to the relay to power the fans when the coolant temp reaches 220 degrees or when the ac pressure reaches 200 psi on the high side.

Where on the intake is the fan control sensor for a 1997 grand voyager


I am assuming you are meaning cooling fan. Your cooling fan is operated by your vehicle computer, via a coolant temp sensor. Not coolant temp sender!!! The sender goes to your light or gauge. The sensor goes to the PCM, which operates your cooling fan. The first thing to do is check your fan to see if it works. Unplug fan and wire two wires, one to one side of fan plug in, one to the other side of plug, one goes to positive battery terminal, one wire to negative. If fan comes on, you have a bad sensor or relay. If fan does not come on, replace fan.

1997 Grand Voyager overheating


check the fan control sensor in the intake manifold. that is usually the problem. also, if the engine cooling fan does not come on when you turn on the air cond, that is a dead giveaway that the fan sensor is bad.
