Adding dash controls to my '02 Sierra

I was looking at some newer model Sierras and saw that some had dual climate controls. I have always wanted to add steering wheel radio contols to my '02 but I think the labor is way above my pay grade. However, I know that the stock stereo and the AC controls are just snapped into place and wired with quick disconnect plugs. I'm not sure which model year the dual AC controls became available. Would my '02 have the wiring harness that would allow me to change my existing AC controls to dual climate controls? Also, could I plug a 6 disc CD changer into my existing stereo wiring?

My truck is a 1500HD, SLT, 4x4, Crew Cab.

They appeared in 03 when they freshened up the instrument panel. The 6 disc may fit with some minor wiring harness provisions. The HVAC control, no way. There is alot of other crap that goes along with the dual control like a whole different damper and fan system. The duct work is also different. A lot of guys try to swap out the dual manual contro(03 and up) for the dual automatic control and it turns out to be a nightmare. There are speed resistive fan motors, temperature sensors and all kinds of other electronics to deal with. As for the steering wheel radio controls that may be possible. The 2001 Blazers, Jimmys and 2002 Yukon Denalis, and Escalades were available with them on the old style stereo and steering wheel. You can probably look into that.

      Oil Consumption

      By Chuck FB · Posted

      Ok that confirms the extra quart theme they are still going with which must mean they have noted some initial use more so then some engines and probably the bigger factor in all of this probably isn't the engine so much as its the insane distance or OLM that lulls a lot of the driving public into driving their new vehicle off the lot and not even doing one short interval oil change because the manufacturer doesn't say different and if the dealer follows that logic as well. Selling the rarely needing to be serviced concept seems to go over well with the public that wants to get away with as little as possible for dollars spent on the vehicles maintenance and I bet there are 3.0 engines just like other vehicles out there that never have their oil checked by the owner which goes back to why they probably felt the need to add that extra quart to avoid a costly theme.    Speaking of cutting filters open, it was probably over two years ago now that a youtuber who buys vehicles to do longer term reviews and pulls a fifth wheel through the mountains of Colorado on summer trips and that becomes part of the testing. Anyway he had a GM HD with the 6.6 gas and a Ford 250 with the 7.3 gas at the same time and of no surprise the Ford had more power etc but somewhere along the way in the few thousand miles he put on the truck, he changed the oil and was seeing glitter and cut open the filter and yeah, things were not looking spectacular. The truck about that time or soon after seemed down on power compared to what it had been and then threw some engine code, I expect the cam/lifters were failing and so he brought the truck back to the dealer and made some deal to get out of it as he knew it would sit for months waiting on a new engine as they were so backlogged at the time. He kept the GM for some time after that using it exclusively until he sold it after buying his next vehicle to do a review on. Definitely the filter can tell a story when things are starting to go sideways, but it would be a sickening feeling to cut it open and be faced with an ugly mess like that and be running a magnet through the pleats and the oil on the dirty side of the filter and see all the fines sticking to the magnet.    The dealer may have some ideas based on experience as to where that coolant smell is coming from, I would imagine if they can't find it but its smelling they would put dye in it to they could give it a run cycle and use the black light to see where it pops up, if its a hose connection, water pump, rad or even a head gasket etc.

      charm.li (website) has the vehicle-specific diagnostic procedure for that code, you can use to find what the cause of it is.

      Oil Consumption

      By KARNUT · Posted

      It’s at the point of amusement. I’m retired I have time. It’s fun seeing people try to convince me I’m using oil. I’m buying oil at the prescribed time. It gets drained and new goes in. Do I add in between, no. My oil doesn’t even get dirty in 5k miles. I don’t even see any drop on the stick. I check in the same place. All is well.
