I've found a few other posts on this, but no solution...

I have a stock 97 Civic DX Hatchback 5-spd with 104K miles.

One night, I noticed that the headlights and dash lights would dim and brighten randomly, along with the A/C fan speeding up and slowing down. Everything electrical surges. It does it with or without the headlights on. It does just as much at a stop as driving down the road. No change with engine speed. Its possessed.

I'm not getting any "engine light" errors and no blown fuses.

I came across Honda TSB 99-029, which deals with a shorted wire under the intake manifold, but I haven't gotten as far as re-wrapping all the wires.

Has anyone with this problem been able to solve the mystery.

Tks
