I was swapping out my radio for the MVI upgrade to CarPlay and io6 today on my 2014 silverado LT and noticed that the wiring for heated seat controls  was behind the trim piece that plugs into a blank spot on the back of the trim piece (red circles in the picture).   I was wondering if there is a chance I can swap out seats for heated ones (just swapped out the steering wheel for heated one) or if I would have to go aftermarket if I wanted a heated seat.  I know aftermarket would be cheaper, but trying to keep OEM look.  Other idea I had was to get an aftermarket kit and see if its possible to use OEM switch and run the wiring up there.

Hopefully Pgamboa will see this, dude knows so much about these trucks.

In short - No.

I worked on a customer’s truck a couple of months ago. He had the same trim. We brought me heated/cooled seats and I told him that have not had the opportunity to try.

Well, I did try, landing ALL the missing wiring.

It didn’t work.

The heat/cool module lives under the passenger seat. It has a communication wire (Lin BUS #2) that goes to the BCM. The BCM doesn’t have this circuit enable so it didn’t communicate with the module.

After discussions with WAMS (www.whiteautoandmedia.com), we ran out of time with the customer to determine if the BCM could be sent and for it to be enabled.

As for using aftermarket heating elements and the OEM switches, here is a video from@Harlech on what he’s been tinkering with.

Pgamboa, thanks for that info...man that's way more complicated than I would have thought to just use the OEM switches!  Guess I'll probably just get an aftermarket kit and see if I can mount the switch in the stock location.

Hey I have an issue with my drivers heated seat as just the bottom works and not the top, noticed under the seat the wires are hacked. Want to fix then and connect then heat shrink it. There are two black wires with a red line so I’ll match those and see ? Or do I need to find out what they do and match that ?

pgamboa do you know the part number for the heat/cool module? Nothing works on my heated seats except the lights on the buttons and I keep reading that it is likely the module.

      The timing marks are ok, that is #1, you can turn it over until they line up and it won't change anything, the crankshaft turns twice for every camshaft revolution, I have always set up SB Chevs as your pic shows using a straight edge

      Someone's been here before.... There is a receipt for a 3-piece timing set, purchased earlier this year.   Is this picture something, or, nothing?   I have the timing cover off and my crank is perfectly TDC and the keyed gear's locating mark is dead on 12 o'clock.   The cam gear locating mark is also at 12 o'clock. Now, I'm not an expert, but all the install guides say the two locating marks should meet and be perfectly aligned when installing a timing set. The mark on the crank should be dead on 12:00 and the cam gear's mark should be dead on 6:00, and both marks should be perfectly vertically aligned.   I believe the timing gear is keyed or has a dowel that ensures it can only be installed on the cam in one position, so I have to believe the cam is out of phase somehow. At the very least, with a triangular bolt pattern, it can only be installed in one of 3 different positions.   Before I pulled the front cover, the truck was running alright, no service engine soon lights except an occasional P0172 / rich condition. Timing -16 timing at idle (should be +16), and total -35% fuel trim, two conditions I haven't been able to figure out.   In related news, my injector tested pretty well, wasn't leaking, but I had it rebuilt anyway, and it's on it's way back to me.         Along with this discovery, the good and bad:   Good: The oil pan seal appears undamaged.   Bad: -The timing cover has been reused, and the positioning dowels have been broken. That could explain some of the leaking. -Some kind of white paste or grease was used to try to seal the oil pan seal and timing cover (since wiped off..). -Then, someone globbed silicone all over the front of the cover and also buried the ckp sensor in it. But, they didn't put any inside the cover or use RTV to try to seal the oil pan seal with the timing cover (good).

      PF63 Oil Filters Going Away?

      By Grumpy Bear · Posted

      The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.

      It also depends on what criteria someone is using for “best” when talking filters.  Are we going off best efficiency?   Best quality/QC?  Etc. because the two may not mutually exclusive.

      They’re not the same wiz as 10-15 years ago.  QC has fallen pretty hard.  The XP line was never good though in the first place.    https://bobistheoilguy.com/forums/threads/wix-filter-rusted-through.386492/post-6991372   https://bobistheoilguy.com/forums/threads/i-ve-used-my-last-wix-filter.27299/   https://bobistheoilguy.com/forums/threads/looking-for-a-better-replacement-for-wix-51258.403977/   https://bobistheoilguy.com/forums/threads/convince-me-in-using-the-purolator-boss.401537/post-7420147   the forums are littered with posts and examples of not great wix filters the last couple years
