A/C Blower Motor
I have a 77 with A/C. The blower motor blows strong except when the A/C is turned on.
With vent/ heat/ defrost or between Max and Norm I can hear it running strong and blows good volumes of air as soon as the switch is placed on any A/C setting the blower slows down (at least sounds like it) and very little air is pushed through the vents. All speeds work on every other setting. Any advice greatly appreciated. (I had an "expert" re do the A/C). I love paying out the **** for things and having to redo them myself because as the "expert" said "these are old cars you cant expect it to work right"
TIA

Roger, Thanks I figured it out. Cheap Chinese replacement control module when I put it just to the right of either A/C setting works fine when in the "click" position doesnt work. Is there an easy way to check the air blend doors seems I have some ambient air coming in with the cool air. I have adjusted the worm gear adjuster but seems its still not swtching over 100% maybe about 75-80%.
Thanks,
Mick
