Hi all.
I just found these boards as I'm looking for information on my car.
It's a 1993 Cutlass Supreme and while it's a dream car of mine (don't ask

, it does need some TLC.
I've budgeted for all the repairs so spending the wrench time on this car doesn't bother me at all.
I knew the heat wasn't working when I got it, I was hoping that it would be a thermostat issue. But after a 3 minute thermostat repair it didn't fix the problem.
I'm now faced with the reality it's probably the heater core.
The car has an electronic temp control unit.
I understand now that the heater core is under the passenger side dash and doesn't require the entire dash be removed to fix. I'm hoping that's the case because when I repaired the core on my TBird it was very expensive in labor because o fthe many hours it took to tear it all apart.
The heat pushes cold air out of all vent options even when I have the temp set to around 90, and the outside temp is in the 60's. I set it to auto (i've never used an electronic temp control unit before so there's a learning curve for me).
Am I right in thinking the heater core is the trouble? And is this something that I can do myself?
I'm fairly car savvy and I'm not afraid to spend a saturady on it.
But removing the whole dash may be getting into more then I'm use to.
Has anyone else experienced this? And if so, what was the fix?
Thank you very much for any info you can provide.
