|  A/C blower 87 Vette
I have a problem with the A/C - Heater blower, the control is the Electronic control, the blower works when I turn the ignition key to the on position. When I start the car, the blower stops working in all modes. When I shut off the engine and turn the key to the on position it will not work again for hours....There are no error codes in the electronic control. Is ther a relay or something to check? Help! It's hot out there.

HI there, It sounds like an ignition switch at the base of the column. A way to check is using a test light to determine voltage in both conditions. Allthebest, c4c5 | ||||||||||||||||||||

You could also try turning the ignition switch key forward back a small amount, with the vehicle running, and see if the blower starts working. Just be careful not to go to far towards the starter crank position as you don't want to engage the starter with the vehicle running.
