Mine does, and it is weird - I'd guesstimate that there is a 10 degree differential.


Makes life tough on chilly mornings !


( I hate cold weather, anyway.)


Also, on my car, it takes the **** being about 3/4 to 7/8 of the way into the red zone for any heat to be put out - is that normal ?

My '91 Suburban will fry you out of the truck, and at 1/2 slide you can feel the warmth.





Thanks !

do you have a hypertech programmer or somthing that lets you adjust the fans to run cooler? It makes your heater run cooler too.

 

It is set to optimize the factory 195 stat temps.


Their website does not show the specifics, but it seems like fan 1 comes on around 205 degrees as opposed to the factory's 218 or so. I would think 200 degree temps would be plenty sufficient for heat.


I have a 195 stat in the Suburban, and it blows plenty warm.

I dont know? But I know on my 95 and my cousins 94 it blows MUCH cooler.

 

I'm confussed, my heater blows hot air, my A/C blows cold! You should be getting plenty of hot air with the temp selector at full hot. I have to turn mine down after engine warms up. Normally to about the 1 o'clock position. If you are getting different temps. from the upper and lower vents you probably have a sicking HVAC door. These are internal to the HVAC housing and a pain to diagnose and get at.
