vehicle: 2003 Chevrolet Avalanche 1500 Z-66 On Road Edition. All options
New mystery. HVAC blows warm, refrigerant is OK, pressure switch is new.
Now, HVAC control display wont light up?????
Switches work but not the LED display. Removed and cleaned all fuses, disconnected battery for 30 minutes and tried again (no luck).
Took out switch/control/display (word to the wise the plastic snap clips get brittle and break) cleaned contacts. When you plug in the display shows 75 degrees for 1 sec or less and shuts off.
Ideas????? I have searched and not found solutions. THANKS!
