i'm having a lot of electrical issues with my truck. A lot of the dash warning lights are on, but, so far, they don't seem to be affecting the truck. Here's a list of the issues I'm having:
- Anti-lock brake system light (intermittent)
- Emission system light (intermittent)
- Battery light (always on)
- Check gage light (always on)
- Door ajar light (always on)
- Engine coolant temperature gauge doesn't seem to be functioning
- When fuel gauge reaches a quarter of a tank, the truck is out of fuel
- Speedometer will occasionally jump around
- Cab lights inconsistent

I know that's a lot of things to be going wrong with the truck, especially if I'm not noticing anything physically wrong with it's performance. I'm wondering if this could just be an instrument cluster issue? And if not is there anything else that could cause all of these problems? Does anyone know of any simple ways I could check some of these systems myself to see if they're actually in need of repairs, or I'm getting false warning lights.

Thanks for any help!

 

When we get a lot of unrelated problems like you are seeing, it may be time to look at the back of the fuse panel under the driver's side of the dash. Many vehicles had windshield water leaks that produced crazy results due to corrosion at the back of the fuse panel. Let us know what you find.

 

I just pulled the fuse box out to check, and I didn't see any corrosion or signs of water damage, so I don't think that's it. I've heard of that being a common problem though, so thanks for suggesting it

 

I know it is a pain to do , but one thing most of those indicators share is the ground connection. Try moving the ground wires under the dash around it is possible one of them has a questionable connection.
There have also been problems with poor solder joints in the printed circuit of the dash or possible cracked solder connection within the printed circuit board.

 

Update:
I sent the cluster into Circuit Board Medics, and they repaired it and sent it back, but I'm still having all the same issues with it. I'm in contact with them, and depending what the actual issue is they may reimburse me, but they said there were several components that had gone bad in the cluster. So, hanky, how does moving the ground wires around help me figure out what the issue is? And would I be able to see all of the the potentially cracked solder joints under the dash?

CBM suggested bringing it to an Autozone to have them do their free code test on it, and see if that comes up with any issues

 

thanks for the Info
