On my 1990 chevy suburban all my external lights have stoped working . i looked in the fuse box but i do not see a fuse for them. i thought it might be the switch but when i hit my breaks the break lights do not come on . is there a fuse or relay some where else other than the fuse box

Daytime Running Lights are a function of the Body Control Module so there is no fuse listed, although there are a number of BCM fuses in the fuse Box Diagrams that you can check.

However, if one light is normal and the other is dim (but still lit), the problem will not be a fuse as you have power to them. Fuses either work or they don't. The problem will be the bulb, the HID module or the grounds to it. The condensation is a clue has likely caused corrosion somewhere.

An auto electrician has probably come across this before and would be able to do the BCM module and HID module testing with a professional scan tool computer. You really don't want to mess with the voltages in them, or replace parts that aren't needed as they are extremely expensive.

According to this it is a know issue and the gauge has a reset procedure.

How do you reset the fuel gauge on a Chevy Suburban?

Press and hold the "Trip/Odo" button. Turn the ignition switch on and hold the "Trip/Odo" switch for about two seconds. Then, release the "Trip/Odo" button, press it again (do this three or four times), and finally hold it for about four to five seconds until the leveling information shows on the Odometer.Jun. 19, 2021

ACTUALLY ITS NOT A FUSE. ITS CALLED A RELAY IS WHAT YOUR LOOKING FOR. IT'LL BE ABOUT AN INCH LONG WITH 2 PRONGS LOCATED IN THE FUSE BOX INSIDE THE TRUCK

Beau: The fuse box is located under the hood, in the corner closest to the driver. There are two black plastic covers (both an external and internal black plastic one) Take a look at this video, I think it will help: http://www.carcarekiosk.com/video/1996_Chevrolet_C1500_Suburban_5.7L_V8/fuse_interior/replace

ck all fuse in under hood fuse box. RR PRK fuse 10 amps.

You will have to trace the wiring. There is a short somewhere before it reaches the actual horn or light. Horns pull an extreme amount of amperage. The relay may be stuck or the wiring to the switch may be bad. My bet would be a shorted switch or relay.

You still safe there is three area that are protected when this happens , the fuseable link opens up, in the fuse box the ignition fuse, in the batter juntion box a fusable link or omega fuse, and starter fuse, 1990 suburban look at the starter for the omega or fuseable link

Should be located under hood in fuse box.
