Seems like I have had to replace evey interior bulb on my truck, so it's only natural to replace the bulb for the power window switch back lighting. My advice, "DON'T DO IT!"

 

This is for a 99-? NBS Silverado (Power windows, locks)

This took me all evening to replace one bulb. Once I got the switch apart or most ways. (Note that I took the switch assembly out of the truck, removed the interior trim piece, which left the switches and their housing. Pull the switch buttons off, and then the black piece which covers the circuit board.)

I had the circuit board with the switches and the black housing for it, all that I needed to do was remove the housing. This is the piece that the wiring harnesses plug into. But all the pins that plug into the harness are pressed through the black plastic housing, then through the circuit board where they are soldered in place. So one by one I removed them which is a pain, and not nearly as easy as one would think. This took 45% of the time. Once those were off the circuit board was able to be removed from the housing allowing access to the back side where the bulb is soldered. Replace bulb and start reassembly in the reverse order. Which took another 45% of total time, again not nearly as easy as one would think. The remaining 10% of time was everthing else.

When finished I took it out, plugged it in and whoolah the bulb worked (Big sigh of relief), I tried the buttons and all worked but Unlock (Lots of cussing), I haven't looked into the unlock button not working so I'll get to that later, luckily I had a spare from EBAY.

Hope this helps anybody that like fixing something rather than buying new. :cheers:

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
