A/C blower problem 66
Hi All The A/C in my 66 works fine. However when the blower switch is in the off position and the A/C switch is turned on the blower is supposed to start running in low w/o turning on the blower. Then it can be set on low,Med. or High. When the A/C switch is turned on the blower starts running in high blower speed. I have changed the blower switch,theRelay switch, the resistor, and the switch on top of the heater housing. I also removed temporarily the condenser at the blower motor. None of these things have helped. Any ideas would be much appreciated. Regards Jim Lucia

Re: A/C blower problem 66
Even though you changed the dash switch I would still check the contact sequence for the different speeds with a VOM. -

Jim,
along the lines of what Albert is saying. Also check the wires that go into the resistor and switch to make sure they have the correct orientation.
I have put many new harnesess in the had terminal positions wrong and also had original harnesess the someone prior had switched.

Re: A/C blower problem 66
I can't comment on a '66 Corvette, but I was 'blind sided' when I read the theory of operation section from the Chassis Service Manual for my '71... I couldn't BELIEVE the number of differences in the Chevy lineup (model to model) regarding how the blower motor was intended to turn ON/OFF relative to the center console/dash switch setting!Comment
