99 Suburban elctrical problems

I noticed no one has replied I have a 98 sub and have simuliar issues. My blower won't work if it is on hi but all other positions it does. My door locks went out a while ago. Now my hand held locker only works sometimes. Just yesterday, replaced my passenger side running bulb, now the horn doesn't work and the PS blinker light on the dash stays on. Also blinks really fast but no bulbs are burnt out. Also when I turn on my headlights the passenger side does very crazy things, it doesn't light up as it is suppose to. When switching from dim to high beam it lights up on the oppisite sides as the Drivers side light. Have you found any repairs yet for yours?

OK, we took it in to a independent shop. They obviously started by disconnecting the battery, because we had to reset the clock when we picked it up. Anyway, they were unable to recreate any of the problems we were experiencing and so didn't charge us for the check out. Its worked fine ever since, albeit, that's only been a few days. I think the BCM was "reset" when the battery was disconected (just a theory).
