No, I think resistor is next on my list...but the A/C behavior still bugs me....

I replaced it...everything is working correctly except for the A/C turning off when I go to position 3 and 4 on the blower switch.  The "jumper" wire I found on the switch wiring bugs me...I think I'm going to have to dig out the wiring diagrams and find out what else has been fucked with.  I think that the car has been like this for some time, and what someone did was put a jumper from the 4 postition wire to the 1 position wire so that they would have A/C on and the blower working.....

I think my next step is digging into resistor...maybe someone swapped the resistor for a non-a/c unit and thats whats causing this wierdness...I don't know...

No go for me...tried that already...I think I'll try slotting the slider knob first (I have spares)...if that dosen't work..I am cutting the slots longer in the face.

Thanks Ron....I guess I am so used to the simplicity of the Mk1 that all this extra crap that is broken bugs me....those vaccum controls have got to be the crappiest design I have ever seen on a VW.
