I have a 2000 blazer it was sitting for 2 months When I went to drive it the

Heater,radio,4 wheel drive,power windows and windshield wipers don't won't

Work. While the lights and power locks still work. What could be cousing these

Problems?

 

Check your fuses to start. After that it could be that some wires were chewed by mice and causing your issues. Beyond that I have no clue sorry!

 

I checked all fuses. Thanks for the reply

 

Sounds like it could be an ignition switch issue. Check out the link to the Tech Article (DIY) section article on the ignition switch at the bottom of my signature below. I bet your ignition switch will look like the one I took pictures of for that article, specifically the contacts corresponding to the large orange wire at the ignition switch which provides power to all of the subsystems you mentioned.
