AC on 05 Trailblazer


Recommended Posts

This thing is driving me nuts and costing a small fortune. Have replaced actuators in both front and rear, and most recently replaced leaking condenser. Now the thing still occasionally throws "heat" to the passenger side (dual controls) even when set on max AC. Also sometimes fan just doesn't even run, and will just kick on after driving for awhile. Shop guy says they've had similar problems in other TB, but most often in ones like ours that have the dual climate controls. Anyone have any ideas??

Frustrating to have just gotten the thing out of the shop and realize it's still not working right, and I'm questioning how much more we should spend on it before we cut our losses...

I know you just had the a/c serviced but I would be curious to see if there is a full charge of freon in the system. Dual climate GM's like to blow one side hot and one side cold if the freon gets low.

If it has a full charge than I would suspect the passeger blend door acuator.

Remove the trim panel under the passenger side of the dash so that the blower motor is accessible. Next time it does not work tap it with a screw driver. If it starts working replace it. If it still won't work twist the connector at the blower motor. If it starts to work replace it. If none of these work than check for power to the blower. If there is power on both wires than there is a proble. On the ground side (resistor, control head, ground wire). If there is power on one side and ground on the other than replace the blower motor.

    • got this tackled today took about 3 hours to get both sides done. Didnt even get to use a torch....   Thought I was golden with just jacking it up and I could get to everything but no luck. Had to remove the entire axle hub and brake assembly to get to what I needed. Was a pain but still better then taking off the entire pivot arm.    Axle bearings were already greased and in great shape thankfully. Got both leaf springs installed and its ready for the road again.   Probably going to have my electric brakes checked, I am not touching anything with the brake drums. Based on what I saw it doesn't look like my electric brakes have been working anyway. Brakes are nice to have if its slippery out
    • By The way that didn't work either!! Screw it I'll just use the cellular. 
    • It’s done automatically.  You might need an actual person to clear that log in stuff up.   Trash your laptop history if you haven’t tried that already.
    • 😂 yea pretty amazing how b o o b i e s gets flagged, but they can't respond or tell me why I  can't get logged in here on my laptop but I can on my cellular  😪
    • I grilled some brats yesterday, maybe next weekend will the next round...  
    • You got word censored cuz you said        B o o b ies….. haha.   Yeah, no… grilling is on hiatus for a bit.
    • Chicken mine,  melded in Mccormick poultry seasoning for 24 hours.  Grill will get a break till the frigid temps go away!
    • we had some nice weather yesterday and this conundrum was driving me crazy  so I drove up to the house to take another look. I got a bunch of goodies via ups yesterday (cables,  winch ratchet parts, handles, leaf springs etc).   I wanted to make sure the new leaf springs I got fit. I got everything laid out and ready to go. Will be busy this weekend with kids stuff and too cold to fish anyway, but I will try to get back up there again next weekend and get it done. I don't think it will be bad once I get it lifted up.    For anyone in the google verse, the leaf springs are 4 leafs and measure 25 1/4" eye  to eye per Yetti. I didnt want to pay their markup so just got something else comparable rated for the same weight.   I am a first time wheel house owner, this is all new to me. My house didn't come with any handles for the rear cables? I was told this week by someone in the industry that cordless drills do not have enough brake to lower it slow enough and it can damage the cables and the ratchets in the winches.  I put on a handle last night and it is 100% better than using a drill, unfortatenly I found out the hard way lol and will only use the ICNutz to raise the house now.
