Check the starter wiring and the main switch, maybe there's a short that makes the fuse blow.

Ac compressor will not turn on, only rarely and if so only momentarily SolvedSolved

Chevrolet Suburban 2005 Suburban 5.3 L 240000 miles
Ac doesn’t turn on, no Freon leak, has enough, have bypassed low pressure switch on accumulator, no high pressure switch located-(have checked around condenser and high side lines-this is a dual cooling unit. No codes, ac switch does light up when turned on and both blowers are working-could the three cooling fan relays have anything to do with activating the compressor? I did notice that the cooling fan motors do not speed up when turning on ac, and also engine temperature is running right where it should be, at 210 degrees, never overheats

High pressure switch was replaced-was out of sight beneath heater hoses below water pump on condenser line coming from compressor

Check the gap on the clutch. If it is excessive the coil will not pull in especially when voltage is below 13 volts.

Battery drains overnight when car turned off. New battery and alternator charging fine. Can a stuck blend door actuator cause the drain ?

Parasitic battery drain from United States a month ago
I put an ammeter in series with negative post on battery and ground lead to engine. I selectively pulled fuses one at a time to see if there was a change in current draw. Then replaced that fuse and went to the next and on and continued until a fuse caused current draw to go to zero. That fuse was labeled INFO. Evidently it powered the system that operated OnStar and Carphone features in this 2005 vehicle. Those features were outdated and no longer functioned but their system remained powered. Removing the fuse permanently stopped the parasitic draw and did not change anything in the vehicle as those systems no longer functioned anyway.

I've seen the passlock system cause these issues.
Ryan from United States 2 years ago
Another issue if it cranks but doesn't start or runs poorly check the ignition control module. Easy fix ensure you put the white grease on the back of it and it will resolve your starting issues.

Under the hood on the driver's side and by the steering wheel
Colt from United States 3 months ago
The main fuse box is in the engine bay, on the left side. There are two more on either ends of the dash when you open the doors. And I believe there’s one in back for the rear section. If you can get the owners manual, it shows them.

Oil gauge stuck at 80

Chevrolet Suburban 2011  260740 miles
So my 2011 Chevy suburban has been fluctuating on my oil gauge pressure for a while It has finally hit 80 and has been staying at 80. But I have no engine light that comes on when it does it should I replace the oil pressure sensor or what is there a fuse that could actually control the module to get it to stop fluctuating

Fuel pump relay

Chevrolet Suburban 2013  250000 miles
I noticed that the fuel pump relay is missing do you have to have a relay for that? I’ve had other relays stolen a few months ago and replaced them and now I’ve noticed that the fuel pump one is missing. Do you have to have it?

Parasitic draw on radio fuse even after replacing radio

Chevrolet Suburban 2014  130000 miles
Prior to replacing the radio I had to remove the radio fuse so my battery wouldn’t be dead daily. After replacing my radio, my suburban seemed to start with no issues and could sit a couple days and start fine. But after letting it sit 6 days I found the battery dead once again when trying to unlock and start . I replaced the battery 3 yrs ago. Are there other things connected to the radio fuse? No aftermarket parts on this vehicle have been added outside the radio . Any help would be great

Passenger headlight Blinker Issue

Chevrolet Suburban 2011 1500 LTZ 208000 miles
Passenger headlight blinker works intermittently. The blinker bulb burns when the headlights are activated and when I double lock the car with the fob. When I turn on the blinker, the bulb does not blink. The mirror blinks. The tail blinks. I replaced the bulb. Replaced the headlight wiring harness. Replaced fuses. Cleaned connectors. Cleaned the ground. I know next to nothing about cars. I'm a google mechanic. Please help me with a solution. Also, the front passenger tire pressure sensor has stopped working. I recently had it replaced, so it's very new.

Reverse lights and overhead dome lights are out

Chevrolet Suburban 2005 5.3 4x4 z71 225225 miles
The overhead dome lights would flicker for about a month and now finally will not come on. The door lights come on no problem which leads me to believe it is not a door switch because they come on when any door opens. Ive checked all fuses and none are blown. Is there a relay for the overhead dome lights?
Simultaneously the reverse lights are not working and ive checked those bulbs.
