Outside Temp Reading gone bad? V8q

[BustnJustn@aol.com]

Hey All,

The outside temp. reading on my car (90 V8q) seems to be reading the temp for 
Anchorage, Alaska.  Unfortunately I'm in Seattle, WA.  Anyway, it just 
recently started misreading the temp by about 15-20 degrees.  Also, when I 
first start the car it shows up really low and slowly increases to its still 
incorrect reading.  Again, it reads about 15-20 degrees low.
What has gone wrong, and how do I fix it?
Any all or suggestions would be greatly appreciated.

TIA,
Justin Bowers
