Blower vent control problem

Post by MARGR4V3Z »

Ok so I have a new problem. I Just started the car and set it to 60 degrees and it adjust to only blow out the front vents which it did properly. I up the temp 1 click to 65 and it switches to feet? Why Is that? I think that's my problem with it not blowing out of the front vents is because of the electronic controls do not let it at a certain temp. Any help would be appreciated!

No idea why, but the electric climate control on those cars just didn't allow heat to blow out the dash vents. Complete stupid design, but yea, heat only out of the floor or defroster...

Oh really? That doesn't make much sense? Guess we just freeze in the winter lol. So 60 degrees is the only setting that blows out the front vents?

Not sure why only 60 blows out your vents, seems like my old '93 SSEi would blow out the vents up to about 75, but even still that wasn't really hot air out the vents.

When the car is up to temp, I never had any trouble staying warm inside, always had to turn the heat down to keep from getting too hot, just never got that blast of hot air to my upper body.

Well its weird cause sometimes I can get the temp higher like around 70 but then it doesn't blow full out the front vents when its on high and then it will automatically change to feet sometimes when its at a higher temp.

There were a couple members that upgraded their climate control to the 94+ style just so they could control which vent gets the air. I think they just had to swap the ECC headunit and HVAC controller.

I never liked the idea because the 93 ECC lets you view diagnostic trouble codes while the newer ones don't.
