Do you need to know how to remove the heater controls from the dash or the bezel from the heater controls? To remove them from the dash, pull the bezel off above the radio first, then 2 bolts at top rear of radio, pull out radio, then heater controls should pull out last I believe.
I removed the top vent trim first then the trim around the radio. The heater control trim looks like it's held on with 3 tabs on top and 2 underneath but I cannot get it off. At the time of trying to remove it I had the heater control unit lose in the dash so I could move it around to get to the tabs.
Do you have manual temp controls? I've got a wreck with manual controls to look at after lunch. I'll see if the face comes off the controls easily and let you know. If you have auto controls then I dunno.
