Thanks so much for the detailed response,
(quote) Both heat and A/C fans are dead and have never worked in the year that I've owned this car. (quote)
Usually the change-over switch will stop at one end or the other after the engine is shut off. So the fact that BOTH fans aren't working could be bad news. If the heater fan itself is bad, pulling the console, heater & AC system to replace it is a two-day job. But for now, the AC fan is just inside the console so that should be much easier to deal with.
(quote) I was using the basic 12v probe w/ the alligator clip. I must've somehow bridged something but with such a small point, it would seem difficult to do (but trust me, I'm 'good' like that). Will be more careful.
Vacuum lines are one of those mysterious, scary objects I've avoided up till now. Will have to look up how to test them and go for it. In this Tampa heat, let's just say I'm HIGHLY motivated to find a solution to this problem. This is a daily driver car. (quote)
For the newbie DYI-er, I would think wiring would be much more scary. I never heard of vacuum lines causing a fire.
(Quote) With the engine running, I didn't see any movement with that vacuum pod above the gas pedal. Time to bone up on my vacuum line testing abilities. [B]Is it true that without the vacuum pod fully operational that the A/C system as well as the fan will not operate at all? (quote)
With the vacuum lines disconnected from the control-valve, and the engine running, you may be able to feel some 'sucking' from one of those lines with your finger. If there's no vacuum, your best bet is to look underhood for any vacuum lines that go to/through the firewall to see if any are broken or disconnected. Even without vacuum, You probably could get the AC compressor running. But lack of vacuum can disable the AC blower and block it's airflow.
(quote) I very much appreciate your gift of knowledge. I'm no dummy but these cars' HVAC systems require some special understanding that isn't exactly intuitive at first blush. Happy Monday!
