: Climate Control Blower Issue

05-03-13, 03:26 PM
My 1988 Fleetwood has a blower issue.
When the set temperature is close to the actual temperature, the blower will not turn on, e.g. car being in garage.
When it is hot from being outside, it will turn on immediately. Also, after a long run, when car is at set temperature, the blower will shut off, and will not come back on until car interior warms up.
Any suggestions?? I think its the blower module, but that's just a guess.

Most likely the in-car sensor if anything. The in-car sensor and the ambient sensor are on the same circuit.

Pull the glove box insert out and confirm the ambient temp sensor ribbed hose is connected at both ends and is not kinked anywhere. This hose is black and a finger's thickness. It funnels a sample of in car air into the climate control module. If off, it would get a delayed signal, if kinked maybe no signal. It runs from the in car sensor in the upper section of the dash to the climate module.

Okay, thanks. I will give that a try.

The hose was perfect. Tight at both ends, no kinks. Maybe a bad sensor??
