Heater/Blower Issue

[cosancollc]

I have a 94 TC and up until yesterday my heater blower came on automatically. As I drove yesterday I realized that my car was still cold inside and noticed that the heat was not blowing. I can only get it to blow manually and that is if I put the fan on high. Medium or low no air blows...any ideas.

Also my TC tends to have a fogging issue whenever it rains or has just rained. I have to run the defrosters on full to try to keep all the windows clear.

Hi, i also have that problem and it has been working if i keep therm. at 70. It still only blows high once it has warmed up. However, when it is not on high it still is on low I can feel it in the bottom vents. :L

Thank you. is that a sensor or an actual mechanical part that needs to be replaced. Is there any info on replacing it myself?

I can give you a link to information on swapping one in a 2001TC. I have to check and see if it is the same on a 94.

I know it is in the same location in a 95 though. See also this thread.
