Hello, ive done some research on the topic. i am new here to the forum and havent read all of the topics.

I have a 2001 suburban that just rolled over 300K miles. never had an autoride problem besides just maitnance. recently the service light control came on and i realised that the compressor hadnt been kicking on.

the compressor is getting 12v and just not working. i just ordered an arnott compressor, my question is are they difficult to change? is there anything i should be looking out for that will make the repair easier for me? im not nescessarily a mechanic, but i do have knowledge, and a ton of tools.
Thanks!
