Hello, I have a 99 Silverado (newer body style) I’m trying to figure out if I have a bad bcm or fuse box, I lost my wipers, cruse, 4wd, temp gauge, gas gauge, all my warnig light beside check engine (yes there all on because of a deer I hit a few years ago), hvac, sometimes radio, and truck seems to shift weird sometimes. I can get everything to pop back on for a second if I hit the fuse box under the hood but everything stops working if I try using anything I listed.
Could it be back or fuse box or something else? I’ve replaced the multi-fiction switch, looked at a handful of my body grounds and cleaned them, check some wires under the dash, and tried changing the relays.
