    Default Need help w/ wifes 04 trailblazer

    O4 trailblazer w/ L6 engine/ LTZ... 1st.problem is her seat heater on the drivers side. The back works but the seat quit working.. the passanger side works fine.. I checked and there doesnt seem to be a fuse for this..?? where do I begin to trouble shoot>???
    2nd. question.. her A/C ..When you push the button ( the snow flake doesnt show up on display, nor does the fan automaticaly turn on, like my 05 silverado) the air seems cool but not as cold as it should.. I have replaced the 2 A/c fuses and that isnt the problem?? Any ideas?? Please guys any help will be appreciated!!! thanks
    Converted over from Dodge! After driving my wifes Trailblazer I had to get me a silverado! Chevy man now for good!!

    Well in all reality it could be a ton of things. Low pressure switch, The actual chage in the A/C system. the compressor itself..

    Also check the clutch pulley on the A/C compressor to see if the middle part which is the clutch turns with the pulley, when you have the a/c on!

    On the heated seat, take the switch out & check out the wires & for power. If okay your heater element went bad.

    well I messed around with it for a while.. Actualy I think it is just the "snowflake" display thats not working I can hear the compressor come on and off when I pull the fuse in and out while it is running and the temp control is set at 60 degrees.. And when you shut it off you can hear the compressor releasing some air so it is working, and it blows cold air... As for the seat heater I will have to go to the dealership.. I looked under the seat and I think there is less wiring in the space shuttle!!
