I have an 06 Sierra 1500 (classic) with electronic climate control on a snowy morning i had the defrost on and it worked fine for a while then the blower stopped. I have checked on here an saw almost all of the problems of this sort seemed to stem from the blower motor resistor, so i bought one along with the +$100 harness. Here is my problem i took the part in with me along with my VIN # to the dealership they told me that the part was updated so i get it and notice that my old blower module (resistor) had a 3 pin connector going to it and 2 Pin coming out (blk\prp wires) to the blower, the new one has a 7 pin connector with a 2 pin to the blower (red\blk) i don't know if i have the wrong part because of the 7 pin harness or if i have to remove the 3 pin from where ever it comes from and replace it with the 7 pin (it has the plug on one end and loose wires on the other) if so how do i wire this thing up.

 

any help would be great my dealer only had 2 techs in the shop that day everybody else was sick and the folks that were there didn't know.

The old part # is the 52413530 your new part # is 89018778. After looking it up I can see their confusion. If I didn't have your old PN it probably would have been a coin toss.

Mike and Robert thanks guys i'm gonna go see if they'll take this one back and sell me the other one luckily my original harness doesn't have any burnt wires so i should be able to take care of it pretty easy, and i've taken pics of the whole thing so i can post them on here step by step i know some people work better with visuals.

 

Thanks again guys i really do appreciate the help :)

      Gas Prices

      By Grumpy Bear · Posted

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
