The AC/heater (HVAC) system may unexpectedly switch to the defrost mode when accelerating. This system is operated by engine vacuum and should be inspected for any vacuum leaks if this problem develops.  There is also a revised vacuum check valve available to address this concern.

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.

On the 3.9L V6, 5.2L V8 and 5.9L V8 the Oil leaks commonly from the valve cover gaskets, intake manifold gaskets (front and rear), timing cover gaskets, distributor O-ring, and the rear main seal area. Using fluorescent engine oil dye can be helpful in determining the source(s) of the oil leak.

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.

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.

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

One the 3.9L V6 and 5.9L V8 the carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.

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.

On the 3.9L V6 and 5.2L V8 it is often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.

The door glass may separate from the glass lift channel. Our technicians tell us a front door glass channel kit is available to repair the door glass. The repair involves removing the door glass from the vehicle.

The engine may exhibit excessively high oil pressure at cold start up. This may lead to distortion of the oil filter case. Inspect the oil filter case for any signs of distortion. If the case is distorted,  Connect an oil pressure gauge to the engine and start the engine while observing the readings. If the pressure reads above 80 psi, replace the oil pump.

A delayed upshift condition may be experienced for about 1/4 mile in cold weather (32 degrees F and below) and is most noticeable after the vehicle has been parked for 8 or more hours. Our technicians tell us the repair involves replacing teflon governor drive seal rings with cast iron seal rings.

On 3.9L V6 and 5.9L V8 engines, the intake manifold gasket may leak and cause increased oil consumption and a spark knock during acceleration; the gasket should be replaced.

On the 3.9L V6 and 5.9L V8 the engine oil leaks at the distributor can be misdiagnosed as leaks from the intake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.
