Question about Heater
I can't believe I never noticed this. The other day, I read a post about running the heat occasionally to dry out the A/C ducts to avoid mildew build-up. I turned on the A/C and put the heat on max. I could hear the blowers running but absolutely no air came out of the vents. I put it on defog and couldn't feel any air coming out of the top of the dash either. The cabin got warmer so I know something is working, but I still think its strange.

Tried that. When its on Cool- it comes out of the dash vents. When I switch to Hot- I can't feel it.

If you remove the battery cover u can see the blower motor to the rear of the plastic compartment. I had put the battery cover on half-azz once and it was weak air, hot and cold. I later figured out a few days later it was that cause I finished my amp wiring and it worked normal again. Also the cabin air filter is behind the glove box, not sure of your miles might be time for a change. I used the fabreeze scented one, smells niiiiiice

If on Cold- high level of air output through the vents.
If on Hot- No air output through ANY vents BUT cabin does get hot.
