So the 1st item you change in the bacl is the hot & cold system.? My Chevrolet Trailblazer 2003 blowing warm air from the top backside.. NOT COLD..🤦♂️😔.. Anyone/Anybody Prosperous Response Welcome... thank you..
Hey Im try n to get the heater working on my sister s 2004 trailblazer I changed the the Auto heat control and put in a new Resistor under the dash and still no power . I pulled the fuse and swapped it around and nothing.either . The rig has been nothing but a pain in the ass from the time she got it . Now the back hatch don't want to latch . It will run ok and I have been watching it for her. Cause you check oil and it will be fine and the next time it's 2 quarts low almost dry . I don't see any big leaks . Just gone . I wish she could get a different ride . But that is not going to happen
I totally feel u! Lol..I’ve had my 05 trailblazer going on 6 years now and have replaced everything at least once…I’m talking major parts like entire front end..control arms and struts etc…cuz it got so cold at night a few winters back it blew out the seals inside the struts…puddles of some weird goo was under each strut on the concrete…it got to -40 that winter…made me car sick driving the pos…then there’s the deer who have a problem with at least mine cuz I’ve had 3 attempt suicide at the hands of my front end…one of which happened in town! A deer cruising the streets of my hometown looking for a vehicle to head butt…another set of headlights and plastic grille pieces that they charge too much for…this is the third winter the pos heater fan won’t work..I’ve replaced everything so idk why it won’t work…I hate chevys now…I won’t own another ever…pos completely now…lectronic junk…leave the damned heating ran by vacuum! Why they changed it to electronic junk is beyond me…probably some sicko thinking it’s hilarious we get stuck in the winter with no heating in our vehicles…seems to be the thing nowadays
