I own a 2003 chevy suburban and we have a few issues. 1 ) the turn signals down work normal. They work when they want to. Sometimes they will be on doing a short trip and then just stop working. Most of the time they just don't work. It's been going on for some time now. A few years al my husband hooked up green neon tube lights to the truck I learn later he hooked the wire to them into the same are as fuse for turn signals. Well now that wire isn't in there anymore but its almost like it could be strengthen because when I push the fuse in and back and hold it in place the turn signals work. I have read people have fix the multifunction switch and/or replay switch and it's fix it. I would like to know if anyone knows what's wrong with that. 2) our oil pressure gage doesnt work at all I must say tho on a few occasions it's started working but that's few and fair between. 3) we have had about 3 times when we have been driving and the speed thing stops working looks like we're going 45mph but my iPhone app says 65 and it feels more like 65. It's even dropped to 0. Does anyone know of i have 3 desperate issue or maybe just one? What do I do? Could wiring be a issue?

 

Sounds like a body control module
