On my 2002 Trailblazer LTZ, the oustide temperature display only reads at 50 degrees.  What is the fix?  Thanks.

On the upper left side of the radiator support is a thermistor (a resistor that varies it's resistance according to temperature). It is a two wire sensor. GM calls it an ambient air temperature sensor. Unplug it and see what you read. It may say something like OC on the mirror with the sensor unplugged..If it reads OC with the sensor unplugged then the sensor is probably bad. This is a fairly common problem and easy fix. Just replace sensor. You will have to get the sensor at the dealer's part department. Cost is less than $20.

Yes, that was it.  It was a dealer part #15035786 and costs $6.00.  The vehicle had to be driven for the temp to read correctly.  Thanks.

hi

I am searching about any usefull information about how can I install mirror with
temp & Comps indication. I have 2006 LT TrailBlazer but only with Airbag
indication, temp & comp none. When I found your posting "Outside temperature
display stuck at 50 degrees" in this fourm by google search I became very happy
becouse you seem have background knelowdge about blazer electricity and I hope
really you help me. Now I have bought the mirror with temp, comp and airbag
indication. the mirror assembled with compus senser working well but temp senser
is outside the car which means it is not equiped. all what I need where is the
location of the outside temp senser and how can I connect it with the mirror.
help me please in anything, if you have drowing of blazer electricity clearfy
the connection between mirror and senser feed me back. I wait you response.

thank you.

This Pt.# is for the bracket only.  The sensor number is 15047946.  List is $19.90 Trade is $13.94.  The 02 TB does not require the bracket but it comes that way from the dealer.  Installation is very simple.  It's located on the left (drivers) side of the radiator but does not attach to it.  It's out front in the rear of the grille and simply unplugs from it's socket.  Disconnect the two wire lead-in from the sensor and after removing the accompanying bracket from the new one, plug the wires into it and reseat the sensor back into the hole where you removed the old one.  Having small hands halps!

And if there is no current sensor to replace are hte trucks already wired, and if so any idea where the wiring terminates?
