    My AC was only blowing on #3 setting and I took it back to the dealer, they changed the resistor and now it blows on all the settings. The rear a/c is not working at all. The dealer said I have to bring it back up to them (cuz I had to have the truck back that day) that they had to figure out why the back isn't blowing. Any ideas what that problem can be? Also, there is a bad rattling under the truck, under my feet. I was thinking maybe the muffler was loose but the dealer said no. What could be loose and rattling under the truck around the area where my feet is?

It could be a bad rear blower motor, or resistor? theres a lot under the truck that could make noise, have a repair shop check it and make repairs.

03'Chevy TrailBlazer..rear ac don't work, rattling under truck


When the dealer replaced your resistor, they probably unhooked the battery (naturally for safety). However, this can blow the actuators unfortunately, especially if it was set to on when they unhooked and rehooked the battery back up. Pretty common problem. The rattling very well could be your stabilizer bar end links. Grab a hold and try to wiggle, should be no movement. Pretty common for these to go out also. When replacing these, get new ones that are greasable with zirks. OEM's are not serviceable.

Bad Clutch Fan? Rear ac/heat don't work front only works on 4


The fan clutch isnt engaged at all times, therefore it may be normal to hold it in place (not recommended). On these trailblazer's 4.2L engine the fan clutch is electronically controlled. Usually when this vehicle's fan clutch malfunctions, there is a random ticking noise while idling or at a stop, also the "service engine soon" may turn on. As for the the fan speed problem, this may be a faulty blower resistor malf (typical) or climate control unit may be faulty. Hopefully this helps!!

Changed the battery out and now the ac will not


does the air blow at all, that is the first question? If so, then it may be what the last response was, just stuck in one position. If not, then check the fuses, if the fuse is okay then there is only a couple more things to check. Pull the passengers side cover off under the dash, beneath the glove box, locate the blower motor relay/resistor and disconnect the plug (hopefully the plug is not melted to the switch). Use a test light to see if you are getting power from the fan speed switch. If you are getting power from all speed positions then it may be the relay/resistor switch bad or a bad blower motor, but you can rule out a bad blower motor by testing it seperately and if it works then it's the relay/resistor switch that is bad.If it is melted, Chevrolet had issues with this part going out from the beginning and said they had it fixed and canceled a recall in 04. Seems the ground is not sufficient enough and causes the wire to get hot, melting the plug and relay/resistor switch losing the ground and causing the blower not to work. Haven't heard of any trailblazers burning to the ground from this problem but it does cause a bit of a headache since the parts isn't cheap, plus you have to buy their wire harness and plug for about 100.00 and fight putting everything back in since it's up under the dash. They have pleny of feet room and that's just what it was meant for, your feet, not your head, shoulders, and arms. Hope this helped if not maybe it will for someone else. I had to deal with this myself on my 05. Thanks, Dale
