Service VME - Water on Carpet in Front Passenger Compartment - leak

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

This 2001 through 2004 model year Rendezvous and Aztek evaporator case water intrusion message is being sent to all Buick and Pontiac dealers. Engineering has identified a potential water leak path from the evaporator case drain provision on all 2001 through 2004 Buick Rendezvous and Pontiac Aztek models. Under certain high humidity and high ambient temperatures, when the vehicle is being driven for extended period of times using a very low blower speed, the condensation can reach the vehicle and wet the front carpeting. If the owners encounter this condition and subsequent water testing shows that there is no other cause for the water leak, an extension elbow should be installed to reduce the likelihood of any reoccurrence of water entry. The part number recommended is 22542866. This part is also 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 changes to use the new elbow. End of message.

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.
