Donny,Detailed repair instructions for the removal of the HVAC module, including vehicle cross brace, for a 2002 Pontiac Grand AM, can be found in GM Service Information under document ID# 783155. Just log on to "", pay the small access fee, and search by the above document number. Please note this document contains the entire published repair procedure; no further information is available.

GM,Thanks so much for your response. The document you refer to is the document we used. It is woefully inadequate for even the most seasoned technician. If you reviewed it (I will copy part of it into this email for our discussion purposes) there are 3 actual suggestions on removing hardware that retains it. Having now successfully completed the operation it misses at least 10 steps that would make it possible for a tech to remove this part. A diagram pointing to locations of bolts as used in other parts of the document would be a huge help. There is no mention at all that there are bolts on the HVAC Module, firewall, steering column support or at the windshield that retain this very complex piece and many of them are hidden until you remove components that are not suggested in the operation. The long and short of it is that we wound up with 9 hours in a 4.5 hour heater core so anything that would help to decrease the learning curve would be welcome. See the cross brace part of the operation below. I think that this safely makes up almost half of the time in the labor operation and would probably be well served to have a stand alone operation. Thanks again for your time,Donny.

Donny, Document ID# 783155 HVAC Module Assembly Replacement for the 2002 Pontiac Grand Prix has been revised. New illustrations have been added many of these include fastener locations. A link for Steering Column Replacement has also been added. These revisions should help clarify the HVAC Module Assembly Replacement procedure. If there are any other concerns let me know. Regards, GM
