Replace the blower motor resister,it is mounted right next to the blower motor,it has a lug with about 7 wires on it.Just unplug it and remove two screws to remove the resister.This controls the speeds for the blower motor.The blower motor is the cause of the resister failure.Even if the motor seems to sound,and run fine,it is pulling to many amps.

SOURCE: how do it remove the intake manifold?

its easy my friend, take your tools, drain engine oil and coolant, remove left side rocker ornament and air duct of intake manifold, collector,hose wires, harness etc, remove ignition coils, egr tube,intake manifold collector supports and the manifold( right cylinder head only,) remove intake manifold, and replace knock sensor to avoid some trouble in the future
