alright guys im pretty sure i nailed the problem but i figured id ask.

noticed driving the ol ladys 93 gc today that when at an idle with blower on and lights voltage drops into the mid 12s. now when i get going again it goes to about 13.4. now i swapped out the batterys and same effects. pretty sure its the alternator. doesn't have any kind of draw. i noticed the ac is blowing warm and a tad cooler when volts are some what in the mid 13s and in past experiences i know it wont blow cold if the volts are up there.

what u guys think? thanks

edit:when no blower motor or lights it sits at 13.4ish. idles and runs finee

 

voltage won't affect temp.blower and blower speed is the only connection between the two systems. your problem sounds like belt loose or worn, not keeping alt. rpm's up

 

what i ment was blower blows just fine. same speed. i ment not enough volts for the compressor to do what i needs todo
