Naw, no dash. It's pretty easy, did it last week. The passenger side hose on my car was detached and different (flexible and thin-walled) than the driver's side (a rotten foam wrapped wire that I replaced with 7 inches of 5/8 tubing)

Condensate was flooding my carpets, no problems since I reattached the passenger side hose and replaced the one on the driver's side.
