I have a 2000 Zr2 Blazer and my question is about my thermometer. It worked great untilthe other day when it started reading OC. I looked through the owners manual and didnt find any information on this. The compass works fine.
Thanks for the help.

 

Replace the sensor behind the grill. Had the same problem with mine for a few years until I read on here that it was a bad sensor. The dealer wanted $45 just to "look" at it and come up with a solution.

Not sure what a new sensor runs but I picked up three at my local junk yard for a grand total of the $2 entrance fee. Two of the three worked perfectly so now I have a backup if/when the current one goes out.

 

thanks.
I know exactly what and where you mean.
