Anyone one know the location of the heater fan relay in a 91' formula LO3? Assuming in the dash but where? I give the top of the dash a good hit she comes on, I hit a bump she goes off and the vicious cycle continues....

the relay should be right by the blower motor on the passanger side firewall (under the hood) I have a 91 and thats where mine is anyway

Cool! thought I might have to pull the dash. Wonder why when I beat my dash tho it turns my blower back on? Blower should be down at the bottom by the core(Pass.Side) far away from where I smack the dash above the radio is why I thought the relay was in the dash..... IDEAS?

how hard are you hitting it ? there isnt any wires for the heater on that side of the car. they run accross the firewall to the driver side and then under the dash. maybe you have a loose wire or somethin goin on behind the heater controls

could also be a loose connector goin to the heater controls

That might be it? I hit the dash hard enough that my beloved sought after ONCE perfect 3rd gen. dash cracked on A 5' degree morning last winter when I smacked it out of frustration. I needed to get to work...
