  1. A local Chevy dealer sells new trucks which they have installed lift kits, and will warranty them. I spoke to another Chevy dealer and he said there are "GM approved" accessories which will not void the warranty if installed by a dealer. .....DIY installs and "non-approved" parts become a gray area for warranty coverage. A lot depends on the willingness of the dealer to cooperate with you.
  2. It was grounded through the old connections somewhere - possibly in the controller. Your original wiring schematic was not detailed enough to know.
  3. Talked to a friend yesterday. ....His 2021 Sierra w/6.2 (17,000 miles) also died going down the road. He previously had 1 lifter replaced. ...Then all lifters on the Left bank. ....Now they want to change all lifters on the Right bank. Dealer has had the truck for over 2 weeks this time. My friend called GMC and told them to buy the truck back. ....They settled on a NEW engine with a 7 year warranty. He likes the truck otherwise.
  4. There may be other ways of doing this, but this is what I would do. A DPDT switch is available in toggle-switch style or rocker-switch style. ...There will be six terminals and they may be screw terminals or push-on or solder type. The reason for using a Double Pole Double Throw switch instead of a Single Pole Double Throw Switch (SPDT) is by wiring it as shown, you increase the life of the switch and add durability. The switch needs to be DPDT MOMENTARY (it returns to the center position when you release it) CENTER-OFF (no continuity to either pole). ....There are lots of sources online. ....Look for at least a 15 or 20 amp rating. .....Price will be anywhere from $5 - $20 depending on what you choose. Moving the switch one direction will activate the compressor. ...Moving the switch the opposite direction will activate the solenoid valve.
  5. i am not familiar with your system. Will the compressor run only when you want to increase the bag pressure? Where/how is the air exhausted to lower bag pressure? Does the solenoid allow the pressure into the bag, or is it there to exhaust air? Is there a check valve on the compressor discharge to prevent air leakage back through the compressor?
  6. An acquaintance was provided a rental car by his Ford dealer since they had no loaner, and his truck was in the repair shop for an extended time under warranty. ....(This was a few years ago when Ford came out with the aluminum F-150's.) He drove the rental for several weeks and one day he was pulled over by the cops and arrested for driving a stolen car! .....Ford or the dealership never paid the rental company, so the car was reported stolen. Long story short, under threats of lawsuits, he was acquitted of charges and rental fees were paid by Ford or the dealer.
  7. Tax evasion was probably his downfall. Selling vehicle mods shouldn't be a problem IF he labeled them as "Off-Road Use Only," with the usual disclaimer about violating existing laws.
  8. Has anyone experienced, or been denied, warranty repairs after your suspension mods? I have a 2021 Silverado Regular Cab, 4wd, Long Bed W/T. .....The tailgate and bed sides are much higher than my 1998 Silverado. .....Since I bought this as a work truck, it is a P.I.T.A. for loading & unloading anything. ....Although today's trend is to LIFT the trucks, I want to LOWER mine! GM warranty states that suspension mods void warranty. .....I'm concerned if I have non-suspension repairs needed (lifters, electronics, etc) GM could deny warranty repairs. A local Chevy dealer will sell you a new truck with a lift kit installed. ....From what I can learn, this is a "grey area" with warranty coverage. The risk of high-cost repairs if warranty is denied makes me nervous. I'm wishing I kept my 1998 Silverado!
  9. If this link works, it should take you to a list of many 2020 Silverado RPO codes. https://www.gmfleetorderguide.com/NASApp/domestic/rpocodes.jsp?year=2020&regionID=1&lang=1&divisionID=1&vehicleID=21795
  10. The QR code on the door pillar is limited to approx 48 RPO codes. ....To see ALL the codes installed, you need to obtain a copy of the Build Sheet for your truck using your VIN. .....You can get that from any friendly(?) Chevy dealer at no cost. ....It was available online for free, but now costs $50. The dealer accesses the Build Sheet through their GM-Global network online. Apparently, if you don't have RPO FHS, than you do not have Flex-Fuel (E85). This is for 2020: FHS E85 FlexFuel capable of running on unleaded or up to 85% ethanol 1 - Requires (L82) 5.3L EcoTec3 V8 engine. Not available with (ZW9) pickup bed delete. L82 Engine, 5.3L EcoTec3 V8 with Active Fuel Management, (355 hp [265 kW] @ 5600 rpm, 383 lb-ft of torque [518 Nm] @ 4100 rpm
  11. Are you sure you don't have AFM or DFM? Which engine/trans combo do you have? ....Unless your build sheet specifies "without AFM or DFM," or has RPO YK9, you probably have AFM or DFM on a V8. The build sheet for my 2021 W/T does not show AFM as a separate code. ....My L82 RPO appears as "5.3L Ecotech3 V8 Engine with Active Fuel Management."
  12. I don't know if this is your problem, but what format are your music files? My 2021 with IOR radio will not play WMA files. ...I had to convert some of my music files to MP3 files.
  13. Correct! The soft tray liner lifts off. ...Underneath is a single 7mm hex screw to remove. ...Tray has 4 clips holding it in.
