How do you remove the dashboard on a 2000 chevy venture. My A/C vents blow warm air on the drivers side vent. I'm told i need to remove to get to blender doors. Please help!!

 

My Chevrolet dealer told me I needed to replace all my A/C controls because my vent was blowing warm air. They wanted $300.00 just for the part with labor on top of that. The next day my son and I got to tracing vaccum lines and the line that goes to the A/C controls had a hole in it. We bought about 5 ft of vaccum line and run a new line around through the fender and back inside the passenger compartment to the A/C controls. That was in 2000 and it has been working great ever since. I hope this helps.
