I have a 1994 full-size Silverado Blazer, 5.7L, no substantial modifications. the 15 Amp fuse for the brake lights keeps blowing out, minutes after I replace it. the blinkers, tail lights, and all other electrical work fine. the bulbs are good. Hazard lights haven't worked right for a while....could this be related? How do I go about finding the "bad connection" that keeps burming my fuse?

did you check the fuses?

If so, then check the plug on the steering column....

In the fuse block under the hood on the left fender.
Check fuses #25 and #27 both 15amp. There is also
a 15amp fuse in the fuse box behind the trim panel
left of the instument cluster. Check these first. if they're ok, with the key off and the brake peddle
depressed check the stop light switch for power out.
The switch is on the top right side of the brake peddle
If you have pwr. check the junction box located on
the left rear inner frame rail. Using the test light I
forgot to mention on the stop light switch. Test for
power at the dark green and yellow wires. If there's
power there check the sockets. By the way if the
fuses are ok, replace 1 bulb and see if it works before
all the testing. I've seen stranger things happen.
Hope this helps.

I've worked on these the first drove me crazy. its the turn signal switch every thing runs thru these. head lights, turn signal, brakes. except the third brake light. it runs directly from the brake switch. go figuare
