The fuse for my tail lights and dash lights in my 91 Chevy S10 Blazer constantly burns out. I put a new one in and it burns out within a couple of minutes on the road. What's up with this?

you most likely have a wire short or a wire cross. Look for any wires that may have the insulation open and lying on metal. check the battery compartment and the battery cables to make sure they have not been pinched against something sharp. look at any recent parts you have replaced to make sure you have not accidentally smashed (grounded) a wire against the frame. also make sure the fuse is the correct amperage, and make sure that some small amount of debris hasnt lodged itself into the fuse box where the fuse plugs in. (do not attempt to dig any debris out of the fusebox without first disconnecting the negative cable from the battery, then the positive cable.)

91 s10 horn dos't work. What are the most likley problems? I have already checked the horn and it works.

Push the cigarette lighter in and see if it pops back out after 10 seconds or so, if it dosent, or it dosent get hot (dont touch it to find out, just put your hand near it) you have a blown fuse. Check and replace the accessory fuse in the fusebox.

Im having a problem fixing my left tail light on my 91 chevorlet pick up. i checked the fuse and changed the bulbs and still nothing

Check the GROUND circuit on the tail light the connector and at the light assembly.......sometimes you have to run another ground wire.75% chance it's that.

1991 Chevy Blazer dashboard lights are burned out. Can't read

Your dash needs to come out. These bulbs push into a plastic piece that "twists" into the back of the dash board. (About a 1/4 turn) Unless you can get at them from underneath, but I think it's to tight.

From what you just said i dont belive the mechanic checked your fuses correctly.

1998 Chevy S10 pickup backup lights don't work

Yes it screws in on right side of tramission and you will need a 7/8 inch deep socket to remove it. You may be able to clean the old one once it is removed. There is a little ball thatgets dirty and may you can get by with cleaning it. Good Luck. Ed

91 chevy s-10 tail light short

You certainly have a short somewhere, and tracking down shorts are not ever easy. I would check the dash switch itself, especially if it was working fine before and nothing else was done.
