Cabin Air Direction
Both the A/C and heat work fine temperature-wise. However, air will only come out the defroster vents. This started out as an intermittent problem but now happens all the time.
There is a vacuum line that runs across the top of the fire wall under the cowl in the engine bay... off of that line there is a line that feeds the HVAC controls, it probably broke and fell of. It's a pretty small line, maybe 1/4" in diameter.
Thanks. I found the line. Everything seems to be OK outside so the problem must be in the dash somewhere. I'll attack that next.
The vacuum is getting to the mode switch. I don't have the tools to measure its strength though. I'm thinking it's a stuck door or the switch itself. How easy is it to find the switches and how expensive are they?
