Postby Maaxxx88 [OP] » Jun 08 2020, 6:23pm

Hello All,
I have 2006 Chevy Silverado Crewcab 2500 HD Duramax Diesel, the past year or so I have had a bunch of different issues,seems to happen more when it is humid and after it rains.

- seat warmers turning on and off by themselves
- headlights suddenly go out
- radio does not turn of. After truck is off
- rear locks won’t unlock
- AC suddenly turns hot

Any help would be greatly appreciated, thanks in advance.

Hi I would try at first to keep the problem simple, remove your negative battery terminals first ( both batteries ) then remove the positive and check all the cables terminals etc for corrosion, clean all contacts needed or not.
Take this time while the connections are clean and still removed to closely look under the hood for loose connections damaged connectors and locking clips on the connectors.
track down all your ground wires that you can find remove them one at a time clean the cable end and the grounding point scuff up the ground point with sand paper if needed to get a solid connection to ground ( then resemble each ground one by one as you find them and clean them ) do not just start removing the grounds as you find them moving on to the next one you do not want to risk forgetting about reconnecting a ground complicating matters.
Once the grounds at least the ones you find are cleaned and reconnected reconnect the batteries positive at both batteries first then connect the negative cables.
Recheck what problems still exist and get back with us.
