I recently had my windshield on my '93 convertible replaced. In Arkansas the Dept. of Transportation does not require (or doesn't enforce) the requirement to cover dump trucks hauling sand or gravel, thus the collision from a rock hitting the windshield. After the replacement, I noticed that the "outside temperature" display on my automatic climate control would consistently read 53 degrees. When the car was first started the display indicated the correct outside temp., but after a few seconds it would go back to 53 degrees and remain there. Today it was 73 degrees outside and the display stayed at 53 degrees. I think that when the windshield was replaced the sensor, which is located directly behind the windshield, must have relayed the temp. at the time of replacement and it was stored in computer memory somewhere??? I tried disconnecting the battery in an attempt to clear any codes, and it worked. The display is correct and all seems back to normal. Has anyone had this occur or can anyone explain the reason for it occuring in the first place? I guess in the future I will have to be on my guard when following gravel trucks here in this state. I do know that in New England if loaded dump trucks are stopped for being uncovered there is hell to pay - literally!
