Closing Assist/Door Lock Issues Due to Pneumatic System Problems

Problems with the pneumatic system can cause closing assist and door lock issues.

Faulty Mass Air Flow Sensor Causing Erratic Engine Operation and Poor Fuel Economy

One or more door windows may stop working due to a failed window regulator. Replacement of the failed regulator will be necessary to correct this concern.
