Cabin air filter for 2007-2014 GM PICKUPS

14SLTZ71 · July 23, 2016

Here is some good info for those of you wanting to install a cabin air filter.

Problem:

GM built over five million full-size pickup trucks and SUVs from 2007 to 2014 with a cavity for cabin air filters, but with no CAF installed. Why? It is impossible to access the under-dash cavity without bending the filter around the transmission bellhousing. Unfortunately, bending a traditional CAF cracks and tears its frame, allowing ingress of pollen, bacteria, dirt, soot and other airborne contaminants and rendering the filter ineffective.

Solution:

AirSepts new GM Truck Cabin Air Filter features a segmented frame that bends to go around obstacles, then straightens as the technician inserts it in the CAF opening.

Attention: Any changes or modifications to the vehicle should be first reviewed with the customer, and then noted on the repair order with customer approval.

This is for customer satisfaction; this is not a warranty procedure. Condition/Concern

Some customers may comment that dust is intruding into the cabin interior.

If the vehicle is driven primarily in high dust conditions, it may be possible for some residual dust to enter the cabin of the truck through the fresh air intake in the plenum, then through the HVAC case.

Recommendation/Instructions

At request of customer, install a cabin air filter following instructions below.

These vehicles did not come with a cabin air filter from the factory. First-time installation of the cabin air filter will require an installation kit. There are two different types of filter media offered; particulate or carbon/particulate. Refer to the part numbers listed in the Parts Information following the procedure below.

Locate and remove the screws holding the right side lower insulator panel as shown in the illustration above. Refer to Instrument Panel Insulator Replacement in SI.
On the underside of the HVAC case, inboard of the blower motor, locate the groove (2) around the molded-in cabin air filter access panel (1) as shown in the illustration above.
Carefully cut out the molded-in cabin air filter access panel using a suitable tool. Keep the tool inside the groove at all times.

Note: The size of the opening is 10.25” x 1” (260.3 mm x 25.4 mm) as shown in the illustration above.

Important: Once the molded-in cabin filter access panel is removed, ensure the opening is free of burrs and debris.
Bend the top stage and slowly insert the cabin air filter into the HVAC module, with the filter stages (cut outs) facing inboard while the pull strip is pointed down as shown in the illustrated above.

Important: The cabin air filter MUST be flush with the HVAC module access opening as shown in the illustration above.
Install the cabin air filter cover plate hook onto the slot in the HVAC module and press the cover flush while installing the fastener as shown in the illustration above.
Tighten
Tighten the fastener to 1.6 Y (14 lb in).

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

Thanks for more info on this, I was going to change mine today and when I took everything apart I realized that I will have to retrofit an access door.
