HELP - Can any here post the details for ALLdata TSBs?

That's awesome. Do you have access to Preliminary Information (PIs) ? I'd like to get a copy of the following PI:

Missing Pollen or Cabin Filter -... #PI01797 (the Document ID is 1464490)

Thanks!

Missing Pollen or Cabin Filter - accessory air heating HVAC condition automatic bilevel blower cool cowl defrost dirt door duct evaporator external fan heat heater manual no odor passenger #PI01797 - (Feb 26, 2004) Missing Pollen or Cabin Filter .

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

Condition/Concern: Missing pollen or cabin filter

Recommendation/Instructions: For 2003 and newer models of the Buick Rendezvous and Pontiac Aztek, the HVAC case does not contain a pollen or cabin filter although the case has the provision and the door is marked "Filter". With the filter removed, air flow into the vehicle is improved when using vent mode and high temp settings. SI and the owners manual do not refer to this deletion or give instructions for installing this filter. Installing this filter may reduce airflow from the IP center vents especially on warmer temperature settings and cause customer dissatisfaction.

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.

Models: (2003-2004 Buick Rendezvous) and (2003-2004 Pontiac Aztek)
