Go to your dealer!!! they are repairing my Equinox at no charge. Do not go to a local mechanic as they do not even know this.Regarding the 2006 Equinox heater not working problem (blend door defect)...GM designed a repair procedure and implemented a special campaign on 30-May-12 to provide dealers with repair instructions. GM also provided special coverage adjustment so that repairs can be made at no charge to the customer (for 10 years or 193,000 km from vehicle’s in-service date). GM’s reference number for this campaign is number 11135.
I hope this information will be of assistance to you. Please contact your nearest dealer to make arrangements for the repair of your vehicle. If you have already had this vehicle repaired elsewhere, GM has also provided a means to reimburse such costs.
Hope this helps all of you, my car is over the 193000, so I'm having to take a different approach. Areas I am looking at are Sale of Goods Act, Consumer Protection and GMs own promises, commitments to customers etc from their own wep sites.
GREAT POST MICKI!!!
