Hey all
just signed up. i got a 200$ Bravada for my son plan is to get it tip top for him next year.
i know very little about this car from what i found out so far blower motor was uninstalled i installed a new one it runs constantly even with key off and out any idea what would cause that?
Upon starting the car all lights on dash flash like it was a bad alternator there is a brand new one installed but all lights flash and i get nothing on the screen or any reads on gauges not sure what will cause that.
after installing a new battery i went out to start it a few days later but i'm assuming there is a draw some where maybe the blower motor?????
i drove it around for a little and it stayed running but did the whole all lights on dash flashing thing a few times but when i went home and parked it i put it in park and i started to roll back kind of like it was in neutral?

I did order a new ignition switch.
a buddy of mine was telling me about a speed sensor to he said he thinks the blower motor might be tied into that not sure i did not order that yet.

any ideas would be extremally helpful

Thank you
