Windshield wipers

Chevrolet Silverado 2016 Wt double cab 4X4 5.3L V-8 with auto  69000 miles
Wipers do not work, will not move or anything? The monkeys pump works,washer fluid, bur nothing. Checked out all the fuses and replaced them was told to check the wiper relay but having a hard time finding it? I was told several places to check but haven't checked under the dash on the driver's side because I have to pull the whole dash apart? Is there a way to take the fuse block out from the left side dash? Was told it might be able to get to it?

Well I replaced both of the wiper relays and the multifunctional swich but still no wipers. I have power to the wiper motor but they don't move. Now when I turn the wipers on the headlights come on? So I don't know what elae to do. Maybe replace the wiper motor? Any suggestions from anyone.

I have a new BCM from the Chevrolet dealer but its not in the truck yet because it needs to be reprogrammed. I talked to a serves technician and that's the problem.
Larry from United States 6 months ago
I had the new bcm module put in and reprogrammed and still no wipers. I have an Obd2 code B 3875-02 and B3875-04 and not sure what to do now. My 2016 Silverado 1500 WT now has 86,638 miles on it and not sure what's next. According to the service manual for the truck , the wiper relays are integrated into the fuse block under the hood on the driver's side and need to replace it! That is alot of money for someone to have to pay at once, but that might not fix the problem.
I have a compustar remote start system and was told to possibly have the control module for it updated and then try and reprogram the bcm module ! I am lost for words to see what is next to do ! Any suggestions would greatly appreciate it.

Replace the fuse box as there is a board in it that gets hot and shorts out.

Trailer light brake, turn light do not work.

Chevrolet Silverado 2016 Silverado High Country 3500 999 miles
Fuse is good. Issue at fuse box or could it be relay? When headlights are on, running lights work.

No crank, no start

Chevrolet Silverado 2003 Silverado 2500HD, vortex 8100 268000 miles
Understood fuse box cover is missing so unknown correct placement of relays and correct fuses. Someone was guessing and able to start truck by swapping relay positions. Worked a couple times then had to swap them back again, which worked then quit, now they jump it sometimes. I got the truck used and just want it to be done correctly, can I get a diagram please of correct positions and maybe wiring of starter system? Especially ground wires. My guess is the jiggling of relays was what actually was helping like a short maybe or corrosiin. Appreciate any feedback, I obviously can't afford a mechanic and have limited skills.

TCS/thermostat

Chevrolet Silverado 2014 crew cab, 5.3, LT 160000 miles
Good day, I have had to replace CTS(coolant temperature sensor) (several times) and thermostat(once) in order to stop my radiator cooling fans going off full blast and not turning off after shutting engine off. I have enough coolant; truck does NOT have relay for fans, it has fuses, and they are good. Please advise at convenience and thank you.

Silverado won’t start

Chevrolet Silverado 1997 5.7 250000 miles
Truck was running fine. Changed out the 4L60E transmission with a newer one. Put everything back together and now the engine won’t start. It’s turning over but not starting. I don’t think it’s getting power to the fuel pump. Have changed the fuel pump relay. Any suggestions would be greatly appreciated

Window issue

Chevrolet Silverado 2000 2500 Extended Cab, Vortec 6.0 145000 miles
I'm having a window problem. Neither of the windows has any movement. They are in the up position. Checked all wiring and found broken wire fixed and checked with multimeter and it is good now. I checked all remaining wires in the harness and all are good. Checked motor and relay and both are good so I'm completely out of ideas.

I can’t find the fuel pump relay for a diesel

Chevrolet Silverado 2020 1500 3.0 Duramax 33543 miles
On the diagram it’s calling for relay number 43 but in my fuse panel there is not one that exists. It’s just empty in that location.
