Known Problems

Delayed transmission engagement of 2 to 8 seconds may be experienced after the vehicle has been parked for an extended period. The fix involves installing a drain back relief valve in the transmission oil cooler pressure line.

The blower motor may operate erratically and the blower switch operation has a sticky or mushy feeling, the detents almost non existent. Our technicians tell us that the blower switch should be removed and inspected for overheating. This is common if the blower motor is frequently operated on high speed as the current flow through the switch tends to melt internal the components. Also carefully inspect all of the switch connector terminals for discoloration due to overheating and replace as required. A poor electrical contact at the connector will also cause the switch to overheat.

The transmission may exhibit delayed light throttle upshifts and harsh engagement into reverse or drive. Our technicians tell us the repair involves the adjustment of the throttle valve cable and replacement of the return spring.
The fuse may blow repeatedly for the HVAC blower motor or the motor may stop working all together. Our technicians tell us that can often be repaired by replacing the blower motor switch with a revised switch and installing a wiring harness with a relay assembly.

A surging or bucking during acceleration can be caused if the distributor is moved or mis-indexed. This is a result of the cam and crank position sensors being out of synchronization. Wear of the oil pump drive gear can cause similar symptoms because it allows excessive free play in the distributor drive. The distributor drive gear and bushing should be replaced if the rotor tip moves back-and-forth more than 3/16th of an inch when checking drive gear free play.

On the 3.9L V6 and 5.2L V8, rerouting the ignition coil wire and spark plug wires can help solve a misfire and/or surge problem that occurs at approximately 45 mph. A service bulletin was published that outlines the specifics of the repair. It states the rerouting procedure should be performed before other repairs are done for misfires, surging or spark knock.

An intermittent connection in the crank position sensor wire connector can cause poor engine performance or the engine may crank but not start.

An erratic idle, stall on hot restart and/or low speed deceleration. may be caused by a faulty idle air control motor. Our technicians tell us there is a revised IAC motor to correct this condition.

Some vehicles may exhibit excessive fuel gauge movement while turning corners. Our technicians tell us the repair involves replacing the fuel pump module assambly.

Insufficient fuel pressure may be caused by particulate contaminates or other type of substances by-passing the primary fuel pick-up screen and resulting in fuel pump failure. Our technicians recommended to replace entire fuel pump module assembly as two (2) filters, primary and secondary are included with the assembly.

Some vehicles may exhibit one or more of the following: Spark knock complaints when the vehicle is under load, various single cylinder misfire, and surge in 4th gear (around 45 mph). Our technicians tell us that rerouting the coil and spark plug wires to minimize induction effects will commonly correct this condition. If wires must cross during the reroute procedure, they must cross at a 90 degree angle.

This engine may exhibit tappet-like noise(s) and/or excessive general valvetrain noise. The tappet-like noise may move from one tappet location to another. Our technicians tell us that the repair involves the replacement of the link type timing chain and sprockets with a double roller type timing chain and sprockets.

There have been reports of timing chain noise. A stethoscope can be used to help pin point the noise location. If the noise is found coming from the timing chain case, replace the timing chain and sprockets and installing a timing chain tensioner.

Excess cooling fan noise may be caused buy a faulty cooling fan and fan clutch.

The HVAC blower may operate on high speed only. This is commonly caused by a failed blower motor resistor. Chrysler has released a revised part to address this problem.
