| temp/gauge and sensor questions
1985 325e
ok my biggest thing is trying to find out where these items are housed and what their purpose is and perhaps what their relationship if any is.
water temp sensor.<<housed on thermostat housing. blue connector 2 poles
thermo fan switch<<housed on thermostat housing 2 spade connector
thermo time switch<<house behind thermostat housing near valve cover 2 pole connector
temp sending gauge switch<<< 1 spade connector housed on thermostat housing
water temp sender<<1 pole (brown connector) housed ???
if anyone knows the realtionship between these units and eachother or in relationship to the idle control module, I would be greatly appreciative of any passed on knowledge.
my gauge is currently reading but not reading accurately its a whole 1/4 off.
i disconnected the temp sending gauge switch and it just completely went off. so i figure this is the culprit. any other thoughts or suggestions? |
