Need help
 

I just bought a 02 blazer 2 door. Im having a problem with the map lights, dome lights, and the back hatch is not working. the back latch has no power like the lights. and i am having a problem with the garage door opener as well it dosent have any power as well any one have an idea? iv been through all the fuses and replaced all the ones that were bad

Welcome to the forum. How many and which fuses, if you remember, were blown? Have you re-checked them? A short can cause a new fuse to blow as soon as the circuit gets power.

Thank you for the welcom .it was just one a little 3 amp. it ran the door locks and the power mirrors. I have checked the fuses again and I have pulled the deal that holds the map lights to check the connections. everting seems to be in order. I did change the bulbs to see if that changed anything but still nothing.

I would investigate that locks and mirrors circuits for the problem. Strange as it sounds, I've read threads here from members who've repaired a broken power mirror and the interior lights started working again.

ok ill pull out the test light and start chasing this stuff down. any words of advice for me?

I would start by checking all the buttons and switches for what doesn't work and causes that 3 amp fuse to blow.
