2004 denali ac works great in rear but barely blows up
front. Air is cold for both. Just barely any air through front
You may want to check your blower motor that may be the problem. Rear has seperate blower motor
Thanks. I pulled heat and a/c fuses. Waited one minute. Put them back in . Turned the key to power everything up for a minute and then started it. Works perfect now.
