I need to replace the a/c heater control unit in my grandpa's 93 ranger. I pulled it out of the junkyard from a 93 explorer. The dash was already out in the explorer.

So how do I remove the lower plastic panel to get to the heater switch unit to come out? Does it all screw on or is it a combo of screws and snaps?

 

on your 93 (as well any from 87 to 95/96 if you pop out the XL/XLT trim piece (that goes across the dash) it should reveal two 8MM screw things just above the heater control unit and then 4 smaller ones (I think about 4MM??) and you just undo those and then reverse process for install...sorry I can't be more help as I don't have my 95 any more....

 

does anyone know if the OP ever resolved their issue?

 

Yep, got it done about this time last year I think.
