2005 Chevrolet Trailblazer Repair Question
Mileage: 81,500 miles.
Heating problems
Answer
Is the blower motor shutting off on the high setting? Also, have you checked for any vacuum leaks under the dash?
the blower motor is on and stong, I dont feel any leaks but I can check again, could the cabin air filer be clogged? I am no mechanic but thought that may do it, since it is just on top?
The cabin air filter would cause the problem in all positions. To me it sounds like the air flow vents are not fully opening and closing. Have you checked for vacuum leaks under the dash?
DId some more looking into this, it seems to be happening on all settings. The force of air seems to be what I would consider low to mid air force and this is when I am on high. I will turn on the air in car only (which is normally higher air force) and it is just a bit less. I check for leaks and I dont have any. I went to try to look at the motor and the in cabin air filter and dont seem to have the knoweldge to get in there. Any assistance would be helpful.
