I have 2002 trailblazer blower for ac wasn't working checked the fuse no power to the fuse jump power over to the fuse it works on settings 2,3,4 ,and I notice cruise control ,four wheel drive switch and horn not working ??? I need help on this one !!!!
check the fuses of the others devices that are not working for power, if there is none on both sides of fuses you may have blown maxi fuse or a fuse if you have the owners manual check for the location
