Speed is regulated by a resistor usually in air duct for cooling it. When resistor is burnt out only high (wow speed) works. I do not know precisely where the resistor is but it is cheap and easy. You'll be OK.

Cool.. If someone could point in the direction of the resistor, that would be awesome.  Thanks

 

 

 

 

To our brother countryman in Canada,

 

I googled and the concept and the word is it is passenger side under dash in the outlet of the blower. A block with a multi wire plug. They say it is 15.00 or so. two screws.

ps I was in Canada last year and met a lady that thinks we don't like Canadians. Please tell everyone up there we love all of you!!

Thanks again1

This same problem happened to me this morning. I only get heat on 4 or 5.

I'll have to figure out where this resistor sits so I can swap it out.

Changed the blower motor resistor yesterday... $31.00 Candian, taxes in.. 10 minute job.. Thanks to those who provided advice....

 

I wonder what this would have cost had I paid someone to do it!!!

Is this the same fix for if you have air blowing out of the vents when the fan is in the off position?

 

 

 

 

 

I believe when the Fan is in the off position it puts the vents on fresh air and just let's air in as your going down the road.

 

I have a question about regulating heat. My temperature setting has like 1/3 for cool/warm and the rest 2/3 of it is really stinking hot. Anybody have any suggestions????

 

Cheers

For my 2002 Tahoe, the part number was 89018597. The dealer verified. It said was for 99-02 C and K 1/2 and 3/4 ton trucks.

 

 

EDIT: I found more info on the Pace Auto Parts website. It looks like p/n 97 is for 2002 and prior vehicles, and the 96 block is for 2003 and newer. Check to be sure.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
