Why would the outside temperature gauge on a 1999 Buick Regal read a low temp?

Answer 1

first let me ask you to clarify. do you mean it reads low temp or that it reads lower then what the banks and the temp outside is???? I have the same problem on my 1998 Regal. The temperature gauge reads ~ 20 degrees lower than actual. Occasionally it will read correct, but not for long. I can't find any information as to where the sensor is, or the supporting cabling that will help me trobleshoot the problem. JJD Not compared to Banks, but actual temperature readings outside. For example, if it is 95 degrees outside, the regal says ~72 degrees. It used to read withing about 1 degree to the actual outside temp, but now it is at least 20 degrees lower. I have a 99 Buick Park Avenue Ultra, and my temperature gage was doing the same thing the dealer replaced the sensor, located on the left front of the radiator. They charged me $80.00, if I had known where and what to look for I could have done it for a lot less.
