After the fiasco with the turn signal/do all switch and the ignition switch, I don't have wipers,stereo, windows, seat heaters, or climate control. I'm told it's a fusible link, but I'm having trouble finding resources what show where the fusible link/s is/are. Anyone have a visual clue to share?

I hate ta bump my own thread, but I'm desperate! No heat this time of year sucks!

A blown fusible link would kill ALL the power to the vehicle. Does it run at all? What is working (headlights, stoplights, gauges, door locks, power sockets....)?

did you check all the fuses in the main power distribution box under the hood.there usally attached to the main fuse box under the hood.

It starts, and drives. I have headlights, turn signals, interior lights, horn, and hazard lights. That's all I have. The people who worked on it last said all my fuses are good and the ECM is running perfectly.

The cigarette lighter/power receptacle works, but it's because a previous owner wired it directly to the battery and it's always on. I have a job starting this week and I can't go losing time because I cant drive in the rain when it's dark out.

Also, the initial problem has resurfaced (all exterior lights going off randomly when high beams are on).

The fusible link(s) were a quickie theory; if that's not it, I'm clueless. I do brakes, not vehicle electrical.

Looks like you may still be having ignition switch issues. The wipers,radio,wipers,pwr windows are powered by the same circuit from the ign.sw.(RUN/ACC) at the instrument panel fuse block. Likewise the HVAC,cruise,4wd,brake light,rear HVAC are getting their power from another circuit from the ign.sw.(RUN).
1st: Re-Check the 50A IGN-B fuse in the underhood fuse block.
If not the switch, the problem could be a connector in the ign.sw. wiring harness.
2nd: Make sure they are pushed together tightly, and the wires have not been pushed out of the connector.
3rd: Check for power at the instrument panel fuses (wiper,radio,wiper,hvac...) when the ign.sw. is in the run position.

I have brake lights, turning the key to ACC doesn't make anything but the stereo come on, and that's not every time.. I'll check the fuses tomorrow when I have better light...

My guess would be to check your RED+ battery cable. If it's like my 99 Tahoe, you will find another cable attached @ the same connection with a fuseable link made into the cable that goes to the main power box located on the driver side close to the front of the inner fender apron. JMHO so good luck, let everyone know what you find.

I took a look under the hood in the fuse panel on the driver side, nothing was blown. The fuse panel inside, driver side, nothing blown. I'm stumped and rather frustrated because having neither heat nor wipers is crap in the winter.
