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.
