2006 Trailblazer Electrical Issues

Asked by Leah Jun 30, 2019 at 06:29 AM about the 2006 Chevrolet Trailblazer LT RWD

Question type: Maintenance & Repair

Vehicle just died-2006 Chevy Trailblazer What could be the
issue? Just bought a 2006 Chevy Trailblazer 146k miles on
it the end of May. Was driving it home yesterday the AC fan
stops blowing in the front and the battery light comes on
and the message said “battery not charging”. Then like 10
seconds of that being being on the ABS and brake light
come on and it starts making a beeping sound. Then the
battery,and and brake lights disappear. And then when I am
pulling in to my driveway they all come back on. So then I
shut it off and try to get it started and it starts but then
those lights come back on and then also the “no airbag”
light pops up now too but as soon as I put it in reverse they
shut off. So then I try again and this time it won’t turn over
and a minute later everything electrical stops working. No
lights,no AC,no windows,no seats,no dash…nothing. I am
thinking maybe the battery just needs to be charged so I
hook it up and wait for a little bit etc(this next part might be
wrong I can’t remember) and I start it and it turns over and
starts so I rev th engine a little bit but still no electrical
comes on in the inside no lights no blower no windows no
seat the dash wont light up. Whats the issue with this if
anyone can help I really would appreciate it? Frankly I want
to know if this is going to be a couple hundred or a couple
thousand to fix. The vehicle now will start and run but
nothing electrical works inside. No windows,dash wont
light up,no AC,no power seats etc. So then decided to try
cleaning around the battery(battery looks good no
corrosion etc/rust). So did that and tried to start the vehicle
and the headlights came on yet it wouldn't start BUT the
lights on the dash finally. But since it wouldn't start I
hooked jumper cables to the battery and the vehicle started
fine(the shifter was able to be moved to reverse etc) so I
unhooked the jumper pack but after 5 seconds the same
thing happened the ABS/NO BRAKE light came on and then
all the lights on the dash went out. I go to start the vehicle
and nothing it wont start. What could be the issue here? I
don't suspect it could really be the battery because would
that really make the lights in the dash not work? Could it be
that blown 125 fuse or the alternator? I don't see how the
alternator either because once the jumper pack was on the
vehicle started and was fine idling(just the lights)
