Outside Temprature display not working

[MyOldJimmy]

I have been lucky in fixing most of the problems on my used 95 jimmy. However only one thing is haunting me still. I can't seem to figure out why the outside temp reading is always showing as "SC" or "5C". Occasionally it displays 140 degrees.

If I change the temp. sencor, will this fix the problem or is this a bigger issue than that?

Please help....

I can almost guarrantee it's your sensor.
You can do a check by unplugging the sensor from the radiator core bar (in the middle of your grill). If the console displays "OC" (it should) then you know it's the sensor.

p.s. $21 from gm dealer

THank you, I'll give that a shot.
