Hey guys hows, it going? 
Thanks for the info on the sliding door and dash electrics. I was able to get both the sliding door and the dashlights working this weekend. Sure is nice too. Didn't have to spend a dime. However, while fixing these things I was testing some other components and realized I don't have a clue what the correct operation method is. My problems is with the heating/A/C controls. According to my manual there are only three levers, but on my van there are four. Can anyone tell me what the four are? There is also an a/c unit mounted over the bed, but All the fans from the four levers seem to be under the dash.
