Clicking noise from wall in right rear cargo area
My 04 TB EXT started clicking from behind the wall panel in the right rear cargo area and wouldn't stop no matter what AC/Heat setting I had. If the key is turned, it clicks. I was able to look through the vent in the wall panel and see that it is a black electric motor housing - I used a screwdriver to push out the power lead to get it to stop, and just stopped using the AC fans. The numbers I can read through the vent are 47210105 0406831 and under that is AH23012003. From what I can find online, this looks to be a faulty Actuator and a relatively easy replacement. Does anyone have any input on just how complicated this part is to replace, and is its failure indicative of any more sinister problem?
Thanks for any input you can give!
