Hello everyone. i am new here. i am wonderinf if any one can help. I have a 1991 190E 2.6. My problem is that out side temp reads all the time -38. Does any one know how to fix this. or what i have to do to fix this. Any help would be great. Thank you in advance. Also does any one kow how to pull the insturmantel cluster out from the dsah.

Maybe it actually is -38 degrees outside? Jk check the sensor near your front licence plate. It could be a faulty display also.

I dont think its a faulty display. I have a friends that shows -38 on start up of the car and then it goes blank. This happened after the shop removed and sent it to a odo shop to repair it. I think they plugged it wrong thus the negative reading. Does your stay on -38 or does it go blank after a few secs?

 

[rsheth]

Yes it stays at minus 38 all the time.

sounds like its reversed....the problem is yanking the cluster out to switch the switch around. That is not fun....

 

[rsheth]

does the cluster just pull out? And do I just reverse the connection. Thank you for ur help. How hard is it to pull the cluster out. I was told that it just pulls out.

Its actually a bitch. Im sure others can give you directions on how to do it.

The sensor itself may be open, or the circuit going to or from the sensor may be open.

To test if the sensor itself is open:
Disconnect the sensor, and jump the two terminals where the sensor goes. It should read very hot on the dash display.

To test if the circuit going to or from sensor is open:
Find a way to jump the wires together, it should read very hot on the dash display.
