I have a 1993 Chevy series 20 cargo van. I have a job over the weekend and if I can not find the source of the problem by mid day Sat., I'll need to rig up some temporary brake lights.
1. I have no brake lights on the van
2. I have no emergency blinkers
3. All fuses appear good, bulbs good since the turn signals do work.
4. temp guage goes wild, 100 degrees one day and waaaay past 260 degrees the next.
Allowing 200 points for the temp guage, 200 for brake lights, 100 for emergency blinkers.
Autozone guy told me that he once had no brake lights and he changed the brake light sensor by the pedal and still no brake lights and it turned out to be the turn signal switch..........no sure how that can affect brake lights.........
this temp guage was on 100 when I bought it and stayed there and never moved for 5 months. Then last week, out of nowhere, I looked down and it was way past 260 and the needle moved some. Now it is moving around in the 260 area and the area indicated by "red". Plenty of water and not over heating.
