2004 Chevy Blazer dash lights don't come on - 2004 Chevrolet Blazer

Under hood, left side of dash by the door light switch, under the dash high up on the left

Hello Linda! Replacing the HDM relay for the low beams will not trigger any of these problems. If the blower isn't working, you probably need to get a new blower motor resistor (for manual controls) or blower motor module (looks the same) for automatic climate control. To access, need to remove the plastic kick panel near your feet on passenger side. After removed, look up you'll see the resistor, it's about 4" long with 2 small screws in it. You'll also need to drop the glovebox door to remove the connector from the resistor to the motor. Suggestion- buy a pig tail for the resistor also, these tend to melt. Very common problem. The ABS dash could be a bad wheel hub assembly or a hub starting to go bad.

IT IS NUMBER 8 ON THE INSIDE DASH PANEL FUSE BOX LOCATION

Do you have a code scanner? What code does it give? If you don't have a scanner and the car is drivable take it to an autozone and have them hook it up to the scanner to get the code or you can buy a cheap scanner for $50 if the blazer was not running rough before you may have not pushed a plug wire on completely and now the engine is misfiring on that cylinder. how many miles on blazer? the platinum plugs from should be good for 100K miles.

the dash sound's like a fuse, check the fuse box under the hood and in the door jamb on the side of the dash, also check your fuel filter and fuel pump, im betting on the pump because i have a 2001 chevy blazer that has had two replaced and it has 233000km on it!

I had the same exact thing happen to me, I have a 97 blazer and after hours of screwing around with it and several different options... it turned out to simply be the ignition switch.

short in the dimer switch

bad ground at battery or chase.

no dash lights 1997 chevy blazer

when i changed my radio in my blazer i discovered there were a lot of wires that ran through it like my dash lights interior lights and a bunch of other stuff you probably just missed a connector or got two of them mixed up you might have to take out the dash again
