I dont know who cares but you should go to a car garauge
fuel gauge stays on full and the tempreture does not move from cold on ford explorer 1998
Likely a bad ground in the relay
temp gauge is stuck on hot
i change the thermostat and the temp switch but still not working
temperature gauge not working can be caused by a bad temp sensor in engine, a bad gauge in dash, or a bad fuse
If your temperature gauge isn't working the problem is a bad gauge, grounded or disconnected wiring or, most likely, the temp sender isn't working.
there is no gauge that shows trans temp, but there is an indicator light on instrument panel that will light up "trans temp" if abnormal
probably the sensor
Check your grounding on your temp sending unit.
Because they are broken is one reason
220-230
Temp. sensor my have stopped working. Quick and fairly easy fix.
