2004 Chrysler Concorde Problems

The instrument cluster may illuminate randomly to its full brightness and/or the fuel gauge may drop to the empty position. Typically the symptoms are infrequent and the instrument cluster returns to normal operation after a few seconds. An update to the body control module (BCM) will fix this problem.

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).

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.

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.

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.

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.

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

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.

Debris and corrosion in the AC housing may cause the AC evaporator core to develop a refrigerant leak.

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.

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.

On higher-mileage vehicles, engine oil leaks from the valve covers and front crankshaft seal are common.

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.

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.

The AC drive belt tensioner bracket can crack and cause the belt to make noise or jump off the pulleys. The AC system may stop working as well. A cracked bracket could damage the cylinder head; it should be replaced.
