Question about 2000 Buick Regal

2 Answers

Climate control has a mind of its own

The outdoor temperature sensor isn't working properly. It's over 100 degrees outside but the sensor indicates it's 32 outside so the automatic climate control turns the heater on instead of the a/c. How do I fix it or disable it so the a/c comes on...........it's like an oven in my car.

Inspect the ambient temp sensor behind the front grill for rust and corrosion. This normaly creates a default within the module if the sensor is defective.

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

unfortunately the climate control system in your car is totally electronic. the outside temperature system is related to the other problems, most likely there is a problem with the climate control computer, but it could be many things in the system that has gone haywire, there is not any thing you can do to the system with out a scan tool, you might be able to go to autozone and see if they can retrieve the trouble codes from the climate control computer. but not all autozone's can get info from Mercedes-Benz they are kind of a breed of there own, good reliable cars but very difficult to work on and Mercedes very reluctant to give any info on their computer systems to anyone other then there certified dealers.and if you are not very careful with the electronics you can do even more damage they are very sensitive to static electricity.i would not recommend trying to repair the system yourself......sorry

First thing that started the outside temperature reading would flicker and finally settled to the steady reading. Then we started getting cold air on the passenger side and warm air on the driver side. ...


That is two separate problems. The "Flickering" of the outside temperature thermometer might be normal to some extent. Sometimes, the voltage from the sensor is at a point where it could be say, 31 degrees F or 32 degrees F. The display may flicker back and forth between 31 and 32 very rapidly until the voltage changes just enough to go make it go solid one way or the other. It probably does this all the time, but you didn't notice until you were paying attention to the temperature problems inside the car. (One actually has absolutely nothing to do with the other.)

The cracking and popping noises you are hearing from the temperature door and the difference between the temperature on the driver's side and the passenger side are the same problem. Apparently, you have dual zone climate control. This is usually caused by one of the temperature doors sticking and either stripping the gears inside the door control actuator or breaking the door itself. If you have both sides set at "HOT", the side that is cold is your problem-child. This will usually also set a fault code in your climate control module and may make your climate control display flash. (but it doesn't always flash when there is a code present)

Climate control display for Outside temperature


Had the same problem, replaced the ambient air temp sensor in front of the radiator. Cost is like 10-15 bucks. Don't worry if temp doesn't change right away. Took me about 5 miles and then it worked great.

1999 pontiac grand prix gt dual climate control not working prope


The sensor is located near the hood latch area in front of the radiator. If the temp is reading incorrectly, chances are it is defective. You can purchase a new one, they relativly inexpensive.
Disconnect the electrical connector then remove the sensor.
Good luck, let me know.
