A/C Max not making a/c blow harder
It seems like it would be the blower motor resistor but the only schematic I can find doesn give me any details that I need to make sure its the resistor. Anyone have a diagram... I think the resistor is OE so its probably about time to replace it.

Re: A/C Max not making a/c blow harder
Is the vacuum line coming out of the firewall near the distributor hooked up?

Re: A/C Max not making a/c blow harder
the speed of blower nosie does not change, I will check the connection but expect it to connected I get airflow from the top vents..
edit, line connected as its always been. gonna replace the resistor tomarrow or someday soon.

Re: A/C Max not making a/c blow harder
Make sure the switch is sealing since its vacuum operated of it has a leak it may not be switching to the high load resistor

Re: A/C Max not making a/c blow harder
I wondered how and what controls the resistor ... guess I can connect a smoke machine to the vacuum line and it would make it easy to find. I know the new blend door plastic piece is broken again.. lasted all of 1 yr. GM should have sourced it to china.. woulda lasted 2 years
