2017 Tahoe with no air in front of cabin. Only rear.

[TheMaineEvent]

Trying to figure out what’s going on with my Tahoe. I cave no control over the direction of air in the front of my cabin, only the rear.

I’ve changed front blower motor and the resistor to no avail. I have the dash pulled apart to change out the dash control unit and hvac control module, but figured I’d post here before spending more money on possible cheap fixes.

Fuses are all good.

um, have you scanned it for codes? checked operation of the blend door actuators?
need full disclosure of what has and has not been done.

I have a code reader but nothing shows. I called dealership to see about them scanning codes and they 12 days out.

I have not checked anything else.

Just went to a local garage and they said I have a u1510 code, among many others.

according to google that code points to the HVAC control module

Sounds like a control unit or blend door issue. @swathdiver may be able to give you some troubleshooting suggestions to zero in on the source of your issue.

Post the codes, all of them. Ought to be some "B" codes in there.

others???????
need those codes, not just "others"
the 1510 is unrelated to your hvac system
we can't read minds over the internet
