Genuine GM Valve Part# 13596856

Good fit easy to replace.

I installed these on my 07 Chevy 3500 Classic. The installation was easy and they stopped the water from getting into the cab. This was a great purchase and addition.

East install - From the outside of the cab (on the top side of the vent), take a long screwdriver to press down on the top tab on the old part. (Use a rubber mallet if needed.) The old part will fall out and drop on the floor. Clean the old decomposing rubber off the cab around the perimeter of the hole. From the top, I used a wet soapy rag wrapped around a short & narrow piece of plywood. From the bottom of the vehicle, I was able to reach and clean the remaining gunk around the hole by hand. Then from the bottom of the vehicle, slide the new vent in place. The new vent only partially slipped into place. Going back to the top of the vehicle, a tap on the top of the vent with the screwdriver to help seat the new vent the rest of the way.

If you've suddenly started noticing wet carpet in your '99 - '06 pickup truck, you likely have a broken seal on the top of the cab vent. You can take a long screwdriver and a rubber mallet and smack straight down on the center of the top of the vent between the cab and bed and it'll pop right out. The new one will install with just a click. I didn't rip out my interior to get at the old one like some have done. After installing this, my carpet dried up and cab venting is perfect.

Perfect fit for my 06 Chevy. I even put a small bead of caulk around them before installing to insure water didn't leak in again. Would buy again

After some heavy rain fall for a few days straight, I noticed the driver's floorboard was wet. After some research, come to find out these vents fo bad. Parts were OEM and popped right in. Truck has been through numerous washes and zero issues. Many aftermarket parts but stick the original parts

I put together. Easy! Quality is great for the price.

Does not fit my 2006 Colorado cab. OEM is no longer available.I gambled.
