2003 chevy trailblazer panel gages not working and ticking sound behind panel while engine is not on

First I'll ask, do all the dash lights come on when the ignition is turned on? If not, fix the ignition switch first, if they do come on then I'm afraid the stepper motors on your instrument cluster have gone haywire, there are several repair kits for these stepper motor malfunctions available pretty cheap

Make sure that none of the fuses were shorted out during the replacement. Also make sure that all relays were plugged in on assembly.

Weird noise and vibration in the dash when I turn

Your heating system is broke in the dash. The doors or gates that change where the air is to go, has a broken hindge or actuator. Your heat is set to defalt to the defrosters as a safety thing. The vibration, I would say, is your fan & it may have been the thing that started your whole problem. The fan has something wrong W/ it, weather it has dropped, the shaft that it runs on is bad, or it is just going to the bad. To fix, the whole dash has to be dropped so that the gates or doors can be accessed for repairs & the fan, it's half in & half out of the passenger compartment. I've had 3 or 4 dashes out to do this work but it is TIME CONSUMING. Wish you the best, GOD BLESS.....

I have a 2003 trailblazer and the engine fan stays engaged. The temp runs at 210

Jeff, this is a very common problem with our platform. Replace your fan clutch, while you're there, replace your waterpump also, it's cheap and it WILL go out. If you can swing it, buy a Hayden brand fan clutch, or buy one for an 08 or 09', those are better. If you do it yourself, do yourself a favor. Cut a notch in the upper fan shroud where the upper radiator hose is. Will save you tons of time, potential breakage, and frustration.

2003 trailblazer, ac not working

Mine did this once. The entire AC control panel was dead as if it was disconnected.
I made it start work again by reseating the AC fuse in the fuse box under the back seat.
Go figure...
