When useing the a/c on my 97 Chevey Venture van the blower kicks out on #5 (high) it will work on 4 or 3 . #1&2 do not operate at all.

That's a little strange but usually a resistor that may be in the heater box itself. The more common failure is High only from your fan request.

Thanks for the quick response. If I locate and replace this resistor will speed #5 stay on and speed #1 & 2 work again.

If that's the fault it will work normally again. --- all speeds!
