heater wont blow warm air

[85begalttype]

2 days ago it was really warm in the car so i turned the heater to cold air so i can get cool air from the vents, now after moving all the way to hot, it wont blow warm air anymore , only blows cold no matter what setting i have. its the touch button climate control.

i noticed from the vacuum diagram that vacuum line from the cruise control goes into the dash which is also labeled HVAC, would a leaky cruise control module make a difference?

I know this sounds completely stupid.......and I'll probably get totally flamed for it..........but drop the glove box down and reach back behind the control module for the HVAC and just move the wiring around with your hand a bit.

You may be able to notice if any connectors have come off just by "feel" while in there.

I did this on mine a few times over the years when the heat doesn't work and it always comes back for some wierd reason. Mine is the manual sliders rather than the push button controls, but maybe it will work. It's worth a shot cause it's free.

Blend door lever is broken. One of the weak points on the AC/heat on these car. Fairly easy to do and not very expensive either.

how do access the blend door? is it behind the glove box or in the vents in the dash somewhere?

You have to go from the bottom and reach up under the dash. Kind of a pain but it just snaps in. Go to GN/TType and you should be able to find a pic and some instructions on how to do it.
