Ignition Module problems of the 2002 Dodge Ram 1500

1) interior blower fan: (24,000 miles) fan would shut off at times. First told by dealer the air intake was blocked with leaves and they cleaned it out. Two weeks later, I got the recall that the wiring harness for the blower was overheating. I had the dealer do repair for recall. They clipped the two lighter wires and replaced them with two 10 gauge wires. Fan still shuts off due to tilting steering wheel with heavier wiring not being flexible enough. Wires still get very hot. 2) radiator fan control relay: (90,000 miles) check engine light came on and code was for radiator fan control relay circuit. Relay was replaced. 3) engine: (129,000 miles) oil sludge caused oil not to circulate properly causing oil pressure gauge to drop to zero and back up to normal about 4 times. Engine over heated, warping heads and doing interior damage to rods and bearings. Engine had to be replaced with used engine. 4) passenger window switch: (for the past 20,000 miles) passenger side switch works intermittently. 5) parking lights: (149,000 miles) was informed by another driver that I had no tail lights. Checked fuses and relay and everything was ok. Took truck to garage, they checked and could not find a problem. Garage called Dodge dealership, they told them it would probably need the front control module replaced. The garage did not charge me and told me they did not want to just start replacing parts costing over $200 trying to pin point a problem and I needed to take it to the dealership. The dealership checked it and told me I would need to replace the power distribution module and the front control module due to both having an internal short. Why bother having fuses if you can just have circuit boards costing over $200 each blow out? 6) ignition park lock: (149,000 miles) got a recall notice about ignition park lock needing replaced. Dealership repaired. This truck definitely has its share off defects, with the engine and wiring. More should be done as far as recalls.
