which coolant sensors (their location also), affect the temp gauge in the instrument cluster, 1985 BMW 635csi
my gas gauge is working, but the temp gauge is not, and i checked the fuses, which are intact. how many temp sensor(s) control the temp gauge ?
This could go many directions from the sensor to the wiring to the actually cluster being the problem. Here is a DIY on how it works and how its tested.http://forums.bimmerforums.com/forum/showthre ad.php?1653238-New-owner-coolant-temp-gauge-inop
