Could someone please direct me to the posts about HVAC issues?
I have the same year and have had many HVAC issues over the years to resolve (blend and mode actuator faults, temperature sensor problems and a bad blower motor). This site will give you a lot of help if you search "HVAC Park Avenue" or use more descriptive words for your problem as a search key. Your problem sounds like a blower motor, blower motor control module and/or fuse (if you're not getting air flow out of any of the vents when you select each of mode selections). If you're not getting air out of the dash but the defroster and lower vents are working that could be the mode actuator. If the fan speeds aren't changing in response to the fan settings that could be a blower motor control module.
You should have started a new thread here, since this thread is not always relevant to the '92 PA. Anyway, the blower control module for the '92 is located under the passenger side hood, firewall side and on top of the blower box. You will have to remove the fuse/relay cover & then remove the the two nuts on the studs holding the same panel to the firewall, pull back then you can see it. It should have two terminals connected to it & 3-screws to remove. I have some pics of the location, but have yet to find them out of 4-k pics I have. It is easy once you gain access! If I find the pics, I will post later.I have a 92 park ave with dual air, the blower won't shut off even after removing the key. I have to unplug the motor or remove the fuse to turn it off. I believe I have to replace the resistor, but I can't find the location of the resistor. Can someone show me pictures where the resistor is located?
