First, thank you for all the information here. It has been very useful. I am new to the community and have tinkered around with cars since high school in the '80s. I have hada few suburbans roll through our family. Currently we have an '05 trailblazer ext lt that is blowing hot air. The actuators have been changed and are functioning. The compressor clutch is engaging, or at least going on as evident by it spinning. The pressure is good and the low pressure switch has been changed a few days ago. I am wondering what I should do next? I do have a new relay coming in tomorrow, but I swapped out the current one with another and that did not help. Checked fuses and they are fine. Took it in to the shop and they said the compressor needs to be replaced, $1000. Any suggestions before I commit to a new compressor? Thank you and I am glad to be apart of this forum.
