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
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 Those features were outdated and no longer functioned but their system remained powered.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.
Active grill shutters, do not work, dealer said it was
Shutters, I replaced and still have code, I applied power and ground and 5v signal and it’s okay. I need a wiring diagram of the Lin bus and aero shutters,
My Haynes manual doesn’t show any shutters. How
Many nodes on bus with active grill shutters?
I was probing wires at connector to grille shutter and
Didn’t see any power this time, fuse to shutter good
I then checked ever fuse in underhood fuse block
With test light and found fuse # 91 blown, replaced
And shutters work with a scan tool and ck engine light went off and ok now . I am not a mechanic
But very mechanicaly inclined.
Replaced Battery & Alternator. Battery indicator light came on, and vehicle will not stay running. Two or three seconds after cranking, engine shuts off.
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.
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.
I lost power to fuse #20 in the cabin fuse block. Can anyone share on where I can find a wiring diagram for that fuse and where it draws it's power from. I have power to the ECU/PCM and to and from the ignition switch.
Dash lights radio engine died going down road...starter turns motor over but want start. Ignition fuse good fuel pump fuse and relay good. Has fuel in the tank. Sun roof want close and both doors windows want work .04 suburban 1500 250,000 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
I get nothing when I turn key to absolutely nothing I have little power some lights on dash are on.doors keep trying to lock and unlock when I turn the key off and weird odd noises sometimes. I tried all kinds of things check fuses another batter now I get no power at all
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?
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
My rear wiper blade, plate light, and driver brake light is out. But the turn signal that uses the same light bulb lights it up. Is it a fuse or wiring?
I'm guessing the latest chase is my positive battery cable gets corroded or something else? I keep spreading money, but now I'm trying to to search around, any one remember the older Chevy's?
My driver mirror is not working with my turn signal, all my signals work except my driver mirror I also have power to the power mirrors but the led does not work at all. I had my oem mirrors on that I assumed burnt out but even with these new mirrors the driver side still does not come on the connection from the fuse box to the door controls has power but from the controls to the mirror it does not, but all functions on the door controls work any ideas?
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.
I had a wire running from the fuel pump to the fuse box under the hood that went into the fuel relay the stop light thing on the brake pedal was bad. I took it off, and I lost all power and now nothing work.
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.
When I hit around 2 RPMs the car goes into limp mode and reads reduced engine power I have a oil leak that is coming near the exhaust I change the throttle body the mass air flow sensor the pigtail connector and brand new ground wires and change spark plugs and coil packs
