2001 GMC Sierra 1500 SLE EXT cab

Exact replacement. I had to use a rental tool to get the old one off but the new one was easily installed with a large crescent wrench. Simple 20 minutes replacement each side. Seems like it took longer to locate my tools,  get the truck jacked and secured, than it did to replace the components.
(Replaced originals that had 200,000 miles)

Works GREAT! It started up my old 98 GMC Sierra those cold winter mornings without any issues. Thank you! :)

Description said it would fit my truck. It did not match the instructions. The 2008 Sierra does not have the proper features to cut that allow this modification to be used.

This part does not fit a 2012 GMC Sierra 2500HD as stated by both Amazon and the product description.  If you have this truck save your time and money and do not buy this item.  I ended up buying the correct part through the dealer for $55 bucks, shouldn't have wasted my time or money with Amazon.

Bought this part (15809057) thinking it was the driver side of the trans cooler  because GM parts direct gave this # 15809057 but turns out
15809053 is the right number for driver side . LOOKING FROM THE FRONT AT THE COOLER.

I installed this on my 89 GMC K1500

Installed in about 15 min with a wiring adapter it plugged right in nice to have a flat connector also if it had a six pin it would be perfect but you will still need an adapter.

Yes i would recommend.

I have a 2001 Chevy Tahoe Z71 with the factory radio (No Bose system) with tape and CD player. The 16195410 fits perfect on the top On/Off volume knob. Make sure the old metal ring isn't left on the tip of volume stem otherwise the new knob will not go on. Push the knob all the way on the stem until it locks in place. I ordered 16199582 for the Lower tuning knob and it with perfect as well.

Make sure you order the correct set for your truck.  Some models need to have 12 holes drilled!  I had to return the set that amazon said fit my vehicle and it cost me $21.00.
Amazon says this is a crew cab, but it is not!  It's a Quad Cab. Amazon doesn't have an option for a 2011 Ram 1500 Quad cab in their garage!

DOES NOT FIT 2009 GMC SIERRA 1500 EXT CAB!  pigtail for electrical connection too short to relocate as per instructions and tech support (Dorman Products) [SEE PHOTO] ; suppose to relocate behind cab ON truck bed but the pigtail is about 6 to 8 inches too short for that; unless you wish to just put it anywhere (which was suggested by tech support) you can but I should not need to modify the fit just to use these parts; Returned.

The rear fan control went out. Indeed this was the part needed to remedy the issue. Unfortunately it's located in a very bad spot. The GM service manual says you need to recycle the refrigerant and drain the coolant to remove the whole unit in order to replace this module. I SAY NO WAY JOSE! You just have to remove the bolts in the passenger compartment (after you've removed the trim, seatbelt bolts, etc.), then go under the rear quarter panel and take out the 2 bolts located on each side of the A/C and Coolant lines. Those bolts don't come out from the body, but do release the "unit". Now you can tilt the unit over and the Module is bolted to the back of it with 2 small torx bolts. This is a time consuming job, but not really difficult if you have the tools needed. PS: If you've ever heard clicking noises coming from back there, an actuator that controls the vents is broken and you might as well change it while your there. There's 2 of the same actuators there and I changed both along with this module. You have to take them apart to see if they have broken gears inside causing the clicking / malfunction.  My best guess is the Dealer would've charged me over $1,500 to do this job that cost me $190 for all three parts. You can do it and best of luck to you!

Worked like a champ in my Chevy 2001 blazer.  Took under 30 minutes to pull old unit and pop in new one. Make sure when you plug the power plug I. You are careful not to Ben the pins... Ok I will admit I did bend the pins... But u it worked like a champ
