heater blower motor on 1996 cadillac eldorado


very tight but you can clear the engine just moving some spark plug wires and the vacuum controls (controlled units?) right in front of it. when you get the bolts off the blower fan housing and its free to move you just have to rotate it so the flat part can clear the rear valve cover. do yourself a favor and be sure to isolate the problem to the motor (and not the electrical connections or the computer disabling it for something rediculous like lack of a/c charge) as it's an expensive part for a little motor and worse (around 250 i think) if you need end up replacing the entire fan.
