  2. If you can’t light a halogen bulb or it’s very dim then you have a issue with a pinched power wire or crappy ground. One very tiny strand of wire can carry 12v Sent from my iPhone using Tapatalk
  3. Install a halogen light bulb in the power and ground circuits, like a brake light bulb. Have you been working with wiring diagrams? Sent from my iPhone using Tapatalk
  4. You can also put it in manual 3 Sent from my iPhone using Tapatalk
  5. Did you load test your circuits? If the power and ground can’t light up a halogen bulb it can’t carry the amperage required to operate anything else. Seems odd that the entire door has nothing working but you have power and ground Sent from my iPhone using Tapatalk
  6. Sounds like a ground issue if you have power to it. You should also watch the parameters for window activation on a scan tool to see if the bcm is seeing the input, but it probably isn’t because the PDM is probably not grounded. This is assuming you’ve checked power. Sent from my iPhone using Tapatalk
  7. Sounds like you need a distributor, maybe the gear is wore out or it’s not providing enough power in the spark, may be weak. Sounds like a distributor issue. Co workers grand wagoner did this once. Needed a cam too totally wiped it out. Anyways your truck was made just after I was born so I may be useless, just thought I’d throw it out there.

  8. If you’re feeling resistance in one direction then it usually needs a steering gear Sent from my iPhone using Tapatalk
  9. Sounds like you had a worn lifter that made a pushrod slap a rocker arm, and when you fixed the lifter, they most likely threw the pushrods into a pile and missed the damage. Or you have a rocker arm bearing that has failed Or a rocker arm is loose. Or a bad lifter out of the box (it happens) Take a mason jar full of diesel fuel and put it into the engine. That’ll quiet it until your mechanic friend returns. Fellow tech at work did that with his Sierra until he got around to fixing the failing lifter. That took 6 months lol. Was quiet as a church mouse though. Sent from my iPhone using Tapatalk
  10. Without driving your truck, it sounds to me like your torque converter clutch is applied too much for too long until you override it by accelerating. TCC apply starts at 30 mph under the correct conditions. So if let’s say your tcm commands 30% apply at 30 mph but the TCC solenoid valve has a clogged exhaust port, then it can’t dump fluid and ends up applying the converter clutch at 100%, which would give you a ‘always in 4th gear’ type feeling. It would also explain bad gas mileage and lack of power. Anyways, just a guess! -GM Tech Sent from my iPhone using Tapatalk
  11. It needs to be programmed. -GM Tech Sent from my iPhone using Tapatalk
  12. Yep needs oil pump. There’s a bulletin for the spring breaking. It defaults to max commanded when it’s broken so as long as you see some pressure you’ll be alright, however I wouldn’t risk it. If you’re on the interstate and it completely let’s go and you need a tow then you’ll be in a world of hurt. Sent from my iPhone using Tapatalk
  13. +1 what jsdirt said. Needs vlom and lifters. If it’s a southern truck, it’s straightforward. Here in Georgia trucks don’t age, I don’t hesitate to start removing exhausts on 20 year old vehicles they come off just like the day they left the factory it’s great. 5.3’s don’t smoke cams as often as 6.2’s, just be sure to roll the cam over when it’s off to make sure you don’t see anything scored. If it’s a northern truck, you better have a welder handy with some throw away nuts to remove all the broken manifold bolts you’re about to have. Ugh. I hate northern trucks. Anyways, hope we’ve helped! Sent from my iPhone using Tapatalk
  14. No it most likely needs pistons Sent from my iPhone using Tapatalk
  15. There’s a bulletin for that? They didn’t do it correctly. You can remove the two T20 torx screws and pop the lens out. It will be obvious if it’s leaking. -GM Tech Sent from my iPhone using Tapatalk
