Front HVAC environment stopped. could it be fuse box is under the glove box?
What is your question?
2007 GMC Acadia heat and a/c worked great then out of the blue without any error or check lights my HVAC system stops. Its a duel environment front and back . so the back panel works the fan or blower in the back turns but no heat or a/c is generated.
Now the problem in the front the front panel and indicator lights seem ok but nothing turns on no heat no A/C no Blower. Replaced the blower under the glove and the resister under the glove with new ones . NO such luck checked the fuses on top all ok then I see there are fuses under the glove as well. they seem ok but that panel looked a little corroded.... but it has been functioning. huimmmmm what next .
What makes this problem better or worse?
it doesnt get worse the front a/c/ heat and blower stopped working

Hello,
Test the control module for the front HVAC to see if it is requesting the functions that you select.
The control module is built into the front panel that you use to control the system.
You would need to use a wiring diagram to know which wire correlates to which device (blower motor, blend doors, compressor).
If that micro-controller stopped functioning, your issue would be replicated.
