Question about 1997 Buick LeSabre
Blower motor fine. Can't locate the heater relay. Is it possible it could be the resistor. Are there any tricks to removing those three 7/32 bolts that hold the resistor unit in place, too tight against the firewall.
I used a 1/4 inch universal with a shallow 7/32 or 5 mm socket and a 5 inch extension. It is not fun to get to the bolts but it can be done. Good luck if this helped give me a rating.
