Temperature / Climate Control Acting Crazy
 

My car has a weird temperature and climate control issue. It always seems to think the temperature is more extreme than it is. Here's an example - today I was driving home, and the temperature was in the 80s (85 according to weather channel). My car was displaying an outside temp of 102, so the climate control was blasting the AC when it didn't need to. I know the outside temp will usually read a couple of degrees high because of heat from the road, but it shouldn't be off by that much.

I have the opposite problem in winter - it blasts the heat way more than it needs to for the temperature I have it set at. I've had multiple cars with climate control, and it's the first time I've seen this issue. Any suggestions?

I'd suggest you just set the temperature knob to where you're comfortable, regardless of what the temperature readings are ......:iono:

Reminds me of a back-in-the-day story. This small church that my family attended had a thermostat on the wall in the back of the church.

People kept turning it up or down. One day I ask the custodian that if he wasn't worried about the constant turning the furnace on of off being bad for the furnace.

He chuckled and said "no, not really, that thermostat in the back of the church is a dummy ....... it's not hooked up to anything".

The AC has sensors for inside the cabin that are independent from the one in the dash. The dash is just for the outside temperature, and if you park facing the sun, it will hit the sensor straight and show ridiculous 110+ temperatures. Don't mind the temperature number on the AC console. Just adjust it for more/less air volume based on your needs at the moment.

Depending on how I park my car at work, I can get that external temp sensor to show over 125 in car. I feel the external ones need about 20-30 min of drive time prior to getting "close" to outside temp.

Mine does the same thing as yours, it makes the auto temp pretty much useless.

The climate control on full auto will do whatever is necessary to get the internal temperature down to the set temperature as fast as it can. It doesn't care what the outside temperature is.

You can run the climate control in a couple of different ways. If you press the off button then turn on the fan, it's in manual mode like a traditional system. You press the auto button, it's on full auto mode and will do what it needs to do to reach the temperature you set.

You can also set it into a semi auto mode. If you adjust the fan setting, the climate control no longer has the ability to vary the fan speed. It will blow full cold air until it reaches the targeted temperature then mix in heat as required to regulate the temp. Anytime you change a setting, it removes that option from the computer. If you turn off the AC button, then it can't use the AC to cool. If you turn in the recirc, it will stay in that mode.
