The window glass lift plates tend to bend or break and cause the window glass to tilt and bind in the door. The lift plates can be replaced separately from the window regulator. In more severe cases, however, a new window regulator may also require replacement.

Worn sway bar bushings or sway bar end links may cause a rattling or clunking noise from the front suspension during low-speed driving. Though not always the root cause, front struts are often replaced for this condition.

A damaged cam position sensor (or its wires and connector) can cause intermittent stalling, stumbles, or hard starting.

Poor output from the heater and/or engine overheating can be caused by air left in the cooling system after the cooling system has been serviced. Our technicians tell us the proper coolant fill procedure should be used to prevent this problem from occurring.

Door weatherstrips mounted on the body tend to shrink with age, leaving gaps that can create wind noise or allow water to leak into the car. Our technicians suggest the door weatherstrips should be replaced to correct these issues.

Some vehicles may develop a musty odor coming from the HVAC system, Dodge has issued a cleaner/disinfectant and a coating for the evaporator designed to inhibit bacterial growth.

If the ignition key does not turn and/or cannot be removed, a new lock cylinder may be needed. A worn key can also cause similar problems.

Before refilling the coolant, make sure the air bleed valve is open. Follow the proper fill procedure—it will prevent problems with overheating, low heat output from the heater, and possible coolant bottle failure.

A dirty throttle body may cause low engine idle speed or frequent stalling, as oily residue blocks air flow in the throttle when the throttle is closed. Throttle body cleaning may be necessary to correct this condition. Our technicians caution against spraying cleaner directly onto the throttle body as this may damage the throttle position sensor (TPS).

A ticking sound (lasting only two to three seconds) may be heard when starting a cold engine. Worn swivel pads on the exhaust rocker arms are commonly the cause. Worn swivel pads will require replacement.

An under-tensioned alternator drive belt may cause a growling noise in the engine area at low speeds (usually when accelerating from a stop). This is often mistaken for catalytic converter failure.

There was a recall on the brake master cylinder in order to fix a problem that causes the brakes to drag when the brake pedal is not pressed. If the brakes drag, they will fade, causing overheating and increased stopping distance. The master cylinder is replaced under the recall.

Fatigued or broken wires to the output speed sensor can cause problems with the cruise control, erratic shifting, and speedometer operation. This may also cause Check Engine Light illumination.

When a no start condition is caused by a faulty camshaft or crankshaft sensor, related fault codes stored in the powertrain control module (PCM) should not be trusted. Our technicians tell us that under certain conditions a fault code can be stored for the "good" sensor. Care should be taken to properly diagnose this condition.

On vehicles equipped with side airbags, placing articles under the seat can damage wiring. Loose, damaged, or dirty connectors under the seat are frequent causes for intermittent airbag lamp illumination.
