Service VME - Wet Carpet , Odor in Front Passenger Foot Well Area - condensation cool core drain duct evaporator fanHVAC leak moisture seal water

When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.

We have identified a potential water leak path from the evaporator case drain provision on all 2001 thru 2004 Buick Rendezvous and Pontiac Aztek models. Under certain high humidity and high ambient temperature conditions, when the vehicle is driven for extended periods with low blower motor speed, condensation moisture can reach the vehicle interior under the carpeting. If owners encounter this condition and water testing shows no other cause for the water leak, an extension elbow should be installed to reduce the likelihood of reoccurrences. The part number recommended is 22542866, which is used on other General Motors products.

Our current plan is to utilize this part in production as soon as possible and a bulletin is planned which will contain the breakpoints when the production change occurs.

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition, please contact GM TAC for further diagnostic assistance. This diagnostic approach was developed for the vehicle with the VIN you entered and should not be automatically be used for other vehicles with similar symptoms.
