Q: How do I use a multimeter to diagnose a problem with my blinkers and brake lights?
I have a 1998 c/k 1500 chevrolet pick up truck.
The blinkers and brake lights have been acting weird. At first just the brake lights and back blinkers went out. After having a guy at a parts store look at it all blinkers are out now. Even inside of the truck I have no lights blinking. Still no brake lights.
Long story short is I have a problem. I know I can use a multimeter/voltmeter to isolate the problem I just don’t know where to start. What do I set the meter to? Where do I start on the truck?
Any info on this would help alot. Thanks in advance.
A: it would take me too long to guide you through how to completely diagnose using a DVOM, so I’ll just cover some of the normal causes of this problem….
It indeed sounds like a multifunction switch problem. The multifunction switch is the switch that houses your turn signals, hazards, wipers, and cruise control. Your brake light circuits do run through this switch.
With your key on, lightly manipulate your hazard switch, and if your lights start working, you can bet that the multifunction switch is the culprit.
Obviously, make sure the auto parts guy didn’t remove your flasher, then forget to put it back in.
Sometimes, the taillamp modules fail, and have to be replaced. (the module is what you plug your bulbs into). And sometimes, the ground wire for the rear lamp wiring harness is broken or not grounded on the frame, causing only the rear lamps not to work….
good luck….
Q: chevy assembly instructions??
I am using a Chevrolet Motor Division Assembly Instruction Sheet for a 1971 Truck “c-k” series 3975764 with the Title marked as Mirror- Outside RR View. I am trying to convert the the measuring units shown there to inches. Are the basic starting units shown there decimals ?; and if so how do I convert them to inches? Thank you for your time, any help will be greatly appreciated.
A: If you are planning on drilling holes in the door to mount a mirror, first look from the inside of the door. There should be three reinforcement pads welded to the inside of the outer door skin. Use them as your guide by drilling from the inside out.
Q: No back blinkers and no brake lights?
I have a 1998 chevrolet c/k pick up truck.
The front blinkers work fine except now they are blinking fast since the back blinkers are out.
Tail lights work fine. Reverse lights work fine. Everything is working fine except for my back blinkers and brake lights.
I’ve checked the fuse it was ok.
If it was a bad fuse wouldn’t that mean my front blinkers wouldn’t work?
How about a bad blinker switch? Wouldn’t that mean I would have no blinkers, and does that control brake lights?
Any ideas at all or any ideas how I could use my multimeter to locate the problem? Thanks in advance.
Also forgot to mention– Front emergency lights do work and back emergency lights do not work.
I will have to repost this question because the details have changed.
I took it to an auto parts store and some guy walked outside and looked at my truck lights. Long story short after all was said and done I left the store worse than when I arrived!! The only lights I have now are head lights and tail lights! No front blinkers or hazard on the inside or outside of my truck.
oh well… maybe I just need to take my truck to a pro.
A: no brake lights? check the brake light switch up by the brake pedal. blinkers don,t work? change the flasher up under the dash or in the fuse block.
