Hello, I am new to this forum, I just recently purchased a 99 GC Laredo v8 about 2 weeks ago. Everything was going great until 3 days ago. I started having issues with the windows not working, and the gauges clicking sometimes, then yesterday, everything electrical started going haywire. It still starts and drives, but the following do not work: windows, sunroof, heat/ac, turn signals, headlight. The hazards stay on all the time, and the door locks work occasionally. The gauges however are VERY erratic. All of the lights flicker on and off, and the needles sweep side to side (shown in video). Also, when I switch the headlights on, it makes a fast clicking sound. I checked all fuses, relays, and tried replacing the hazard/turn signal switch.
I had a leak under the dashboard, which I think I fixed, and water was dripping down by the fuse box. I am wondering if maybe the water fried the BCM?
Any input would be greatly appreciated.
