Fuze Box Problems

[mwhit135]

Hey folks, im having a heck of a problem with electrical issues, so here i am. First off, vehicle specs.
1995 GMC Sierra 1500 SL, 5.7L engine with 98k miles. The problem started about 4 years ago, yeh... its been a while.
I was driving normal, stopped at a stop light, turned at the green light and click. I lost the majority of anything electronic.
It seems to me that a good half of my fuze box does not get power. SO far on troubleshooting i know that all the
electronics themselves work fine. I went through each terminal and gave them power from a different source by connecting
a wire from a terminal that i knew was getting power (top terminal where 1 side of fuze goes) and lead that to each of the bottom
terminals that had items that werent getting power. This is how i was able to prolong this for close to 4 years, by pretty much hard
wiring things i needed (radio, Wipers AC). Here is a rundown of what terminals are getting power and which are not, also
what they belong to (some may not apply) as worded from the owners manual. If a number isnt listed, it isnt used.


1 - Power - STOP/HAZ -stop/TCC Switch, buzzer, CHMSL, Hazard lamps, stop lamps.
3 - Power - CTSY - courtesy lamps, cargo lamp, glove box light, dome/RDG lamps, vanity mirrors, pwr mirrors.[/color]
4 - Power - GAGES - IP cluster, DRL relay, HDLP switch, keyless entry, low coolant module
6 - No Power - CRUISE - cruise control
7 - Power - AUX POWER - aux power outlet
8 - No Power - CRANK - Diesel fuel pump, DERM, ECM
9 - Power - PARK LPS - lic lamp, park lamp, tail lamp, roof marker, tail gate lamps, front side markers, fog lamps relay, door switch illum, fender lamps
10 - Power - AIR BAG - DERM
11 - No Power - WIPER - Wiper motor, washer pump
12 - No Power - HTR/AC - A/C, A/C Blower, high blower relay
13 - Power - CIG LTR - power amp, rear liftglass, cig lighter, door lock relay, pwr lumbar seat
14 - No Power - ILLUM - 4WD Indicator, LP Cluster, HVAC controls, rr hvac controls, IP switches, radio illumination
15 - Power - DRL-FOG - DRL relay, fog lamp relay
16 - Power - TURN-B/U - frnt turn, rr turn, b/u lamps
17 - No Power - RADIO - Radio (ign)
18 - No Power - BRAKE - DRAC, 4WAL PCM, ABS, Cruise
19 - Power - RADIO BATT - radio (batt)
24 - No Power - 4WD - Frt Axle, 4WD Indicator Lamp

B - (Circuit breaker) PWR WDOS - power windows

Please lend a hand if you can. I have checked all the fuzes i can possibly find, maybe im missing
a hidden one or something... if only it was that simple. Thanks in advance for any help or input. Also i have looked at the following diagrams and only see the 1 fusable link, which is between the battery and alternator. It appears fine, and have no alternator problems so i ruled that one out.

My first thought would be ignition switch. You need to get your hands on a good wiring diagram of the fuse block and ignition switch. Most public libraries offer alldata for free. From there its as easy as checking power in and power out.
