Hi All..
First post here. Any help would be appreciated.
Our '92 Legacy Wagon is a trooper, 260,000 miles and still doin' okay... but our most recent challenge is the heater/blower/area selector...well, that's the official name ;-)... I call it the (pushbutton) control that selects where the heater blows - Defrost (windshield), Heat (comes out at feet), Bi-Level (comes out at feet and through centrally located main vents).
Recently, the air started to blow out the centrally located main vents ONLY. When the symptoms first started, it briefly started to WORK again...blowing air through the defrost vents... but that ended within a day. The dying gasps of whatever was going bad, I guess. Now it only blows out the main vents.
Finally, now that the hot air will only come out the main vents (all fan speeds work fine...so it's not my resistors)... the air comes out the passenger side a lot stronger than it does on the driver's side... but even the drivers side has SOMEthing, as opposed to the Heat and Defrost vents which pass little air if any (the windshield defrosts over about 20 minutes...so there must be some SLIGHT air getting there - probably just peripheral currents).
Okay... so now my question.
Is it more likely that this is a problem with the electronic push button dash control unit... or with some sort of linkage that controls where the air blows?
If it's the former, I'm assuming I'll have to remove the push button heater control unit on the dash and see if I can repair. If it's the latter, I'm hoping I can access the flow tubes or directional gates from under the dash.
Totally willing to get my Novice hands dirty, just need to get some guidance on where to start.
Thanks in advance for any suggestions or tips.
