Question type: Maintenance & Repair

So I have a problem with my Chevy Trailblazer. My lights
seem to go out sometimes when I'm driving or step on my
gas or use something in my cards and my lights dim and
go bright again my radio speakers seem to go in and out
sometimes they work properly and sometimes it's just like
the treble is working but the base is not working and the
speakers  aren't working  properly and now my AC blows
cold air however my fan does not work I can turn it up and
down it doesn't matter I got to have it set on the AC button
when order for it to blow cold air but it does not blow it it
just kind of slowly seeps through the vents my fan does not
work anymore any suggestions on what this might be
please

We have checked the ground under the passenger side panel in the floorboard it seems that it is all proper. We have checked the fuses the ones that we can find to go to it and they all seem to be in good. We haven't been able to find a relay that works for that. We have looked it up online and all it says is that it's probably a ground short but our ground seems to be in good condition.

Think you have a few different problems that we've all experienced in our TB's. For the lights going out, replace the HDM relay under the hood, I think it's # 43 or 46, and keep a spare. The dimming could be an alternator issue. Your fan could be your fan itself or the ever popular blower motor resistor (for manual controls) or blower motor control module (auto controls). Those are 2 different parts, so be careful when ordering, one will not work in place of the other. When replacing this, replace the pigtails too, they melt.
