Does the ac have to work for the heat to work???
frist off you do not have to remove the dash
and your motors are fine. you can replace the motor on the passenger side simple the driver side is hard to replace without removing the dash
52 = AI (Recirc) door travel range too large
54 = Left temperature door travel too large
56 = Right temperature door travel too large
54 and 56 is the broken blend door
there is a simple fix that you can make a hole behind the glove box and change teh broken parts in under an hour.
i did a write up on it and its not had look http://www.jeepforum.com/forum/f13/d...p-pics-884932/
the cheapest kit now adays that lets you keep dual control is sold by jeep for $100 and under
part number 68080867AA Mid-Case Blend Door Housing Repair Kit - Item # 68080867AA & 5134353AA
now for 52 you have to remove the dash to replace the door. but what most people do it just keep it prompted open all the time. some drill a hole in it and tie wrap it to the grid and other screw a pice of metal to hold it up.
can access it from the glove box aswell but on the otehr end and more up
this link has some pics and info http://www.jeepforum.com/forum/f310/...x-pics-347814/
the kit should work for you but email the guys at justforjeep or go to your local dealer and ask why they say 5134353AA is only for 02-04 and 68080867AA is for 99-01
hope it helps and dont go back to that mechanic for this help. it could be he is just outdated on how to fix this or was going to do the threw the dash fix and charge for removing the dash.
when i had first had this a local shop gave me the price of $1600 for labor and parts and wanted to flush the cooling since even though they were not touching anything that involved it in my jeep since another model with dual control said too. since i did not want to spend that i did not have heat on the passenger side that year then did the fix i did a writ up on.
