.. i found the easyest way is just remove the dash itself.no to hard, 2 wing nuts just above the heater box, and 2 screws/ bolts ( one one each size of the dash)lower end next to the doors,,one has lots of grounds on it( the driver side), just tkae notes on all the wires when you unplug them. taking the heater box out after you take out the dash is much easyer....after you take out the heaterbox, and take it apart to clean, drill a few holes in the bottom 4/5 mm holes willl work, this will allow any water to drain out.. and after you put it all togeather, get a section of screan( as in screan door mat.) and glue it tp the top of the heater box,this will help in not letting any leaves/twiggs. mice etc. from droping into your nice clean heater box.
