Front AC and heat wont blow in front, panel is up and running but nothing happens. Rear works fine. Do I start with the blower or compressor? Thanks

 

do you mean there is no airflow from the front hvac system?


with the key and front blower fan switch turned to high...hammer fist the blower motor....if it starts running, you need a blower motor.


If that does not work, check for power to the blower motor. Unplug the blower motor connector and check for power and grd with key on and blower switch on.

 

Ok. I got nada. Only air coming thru is at highway speeds and it's not cold and not strong.

 

Hello crc419,

I'm sorry to hear that you're experiencing concerns with the air conditioning in your Suburban. I certainly understand how frustrating that is, especially with summer quickly approaching. While I recognize that you're taking a do-it-yourself approach, if you decide to take it to a dealership for diagnosis, let me know and I'd be happy to assist.

Have a great weekend!
