Why would a 1997 200SX SE-R temperature gauge drop to zero with the car in motion and the heater fan on low?

It could be a short on the guage pod, a blown fuse all by itself... Could also be a bad temperature sending unit (burnt out or lost contact) Could also be an ECU problem... I would have it diagnosed by the dealer or buy/find a Factory Service Manual and attempt to check the wiring via the wiring diagram in the FSM. I had my guages go dead when someone installed a new header of all things.... it was a fuse. Hope that helps a little....

Your temperature gauge fluctuates when you turn the heater on?
Temperature gauge may drop when heater turned on because additional coolant from heater core is introduced to cooling system - usually this coolant is cooler than what is currently circulating
Why does the temperature gauge show hot but the car does not over heat in a 1997 Honda accord lx 4 cylinder?
A short between the heater switch and temperature gauge.
Why does the Temperature gauge goes down when heater is on in a 99 ford contour?
Thermostat probably needs to be replaced.
What should You do if you're temperature gauge moves up to just below THE red zone?
Turn on your vehicle's heater
Just bought a 1996 200sx auto and noticed temperature gauge sitting high is this normal?
I own a 95 200SX SE and it sits around cool range. Below half on the guage. I would say its either the thermostat, Rad has a plug somewhere, or the water pump is weak.
Why would a 1999 Nissan altima temperature gauge fluctuate and car is not overheating?
My Altima had that problem and it was the water pump going out. It started with temperature gauge was moving, but then it started leaking and finally the heater stopped being warm at idle.
Could someone help. I have a 1992 Buick Rivera and the temperature gauge in car is going toward the red I turn off the heater and it drops away. is it some kind of sensor heater core thermostat?
The heater core may be plugged or not flowing properly. This would not allow the water to flow properly to cool the motor. Also you may have a bad or loose ground wire to your heater switch, this will give you a false reading on the temperature gauge.
Why would the temperature gauge drop when the heater is truned on?
The heater core is just like having another radiator, only smaller. Once you turn your heat on, and force air through the heater core with the blower motor, the engine's coolant's temperature is lowered, and circulated back to the engine, probably right where the temperature sensor is located.
Just had intake gasket fixed then turned around and had to get the heater core fixed now it is not blowing out hot air out of the heater why?
Check the temperature gauge. If it is running cold, replace the thermostat.
Why does the temperature gauge act erratic goes from cold to hot quickly then drops to cool When in red there is no heat from heater When in cool there is hot air from heater?
Low coolant, check when engine is cold.
How do you fix the gas gauge on a 1988 Nissan 200sx you have the float you just bought the car and the gauge does not work?
check the wiering /our your sending unit no good
If a 2001 Grand Am GT temperature gauge doesn't show anything but is generating SOME heat but not a lot are we looking at a thermostat or heater core?
neather temp sending unit or faulty gauge....
