Hi


Thanks for using FixYa. Try and check if the heater core is plugged. Find the 2 coolant lines going to the heater core. They are right next to each other with approx 3/4" hoses going to the engine. Now, warm up the engine with the heater on max (don’t turn on the fan). Next, feel if the hoses are warm (maybe HOT!) If they are not warm, then you most likely have a plugged core. A back flush will resolve the issue. If your hoses are warm, turn on the fan. One hose should go cold (or cooler than the other, actually should be about the same temp as the air from your air vents, if there is a plug). If both hoses are hot and stay hot, and you have no heat, then the problem is not with the heater core but with the blend doors.


There are electric motors that operate the "blend doors" inside the dash directing air flow from the heater core and A/C evaporator core to the cab of the vehicle. If you feel a drastic difference in one of the radiator hoses, then try replacing the thermostat and see what happens. If all the heater and radiator hoses are pretty much the same temperature I would suspect a control problem in the dash controls or in the blend door operation. You’ll need to remove the dash to check these.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks
Rylee

When i turn on the AC there is a clicking noise from the engine 2004 trailblazer. when i rev the motor the noise also increases in speed. when i shut off the ac it stops and runs fine.


This noise is probably the AC compressor cycling on and off because the system is low on refrigerant. The reason it is low is that there is a leak, this needs to be repaired by an HVAC technician.

2004 trailblazer truck surges and shuts off when AC is turned on. This is not an compressor or freon problem because with foot on padel ac system works and cools very well.


It's your automatic A/C Clutch bearing. The computer tells the clutch to engage and it connects to the compressor but the bearing is shot and attempts to seize thus slowing the motor. I would not run the A/C until the unit is repaired.

I was gone for a week when I got back my 2004 trailblazer's battery was completly dead. I was able to get a jump and recharge it. it ran fine for a day then the 2nd day out I tried to jump someone else and...


Could be a blown fuse. While jump starting the other vehicle, you could have had a surge of voltage. A bad fuse could be the result of this. Hope this helps. Good luck
