well i was thinking i might have to do that untill i found a video on youtube showing that the aftermarket heater core comes with swivel lines . i disconnected the saftey clips on the AC lines and had just enough room when i pulled the heater box away from the firewall. i had to hacksaw the old heater core lines off to get it out the housing as they dont swivel like the new one . took a couple of minutes routing the new lines through the firewall but it all went ok . if it wasnt for the swivel lines i would definatly have had to take the AC lines apart . the hardest job was taking the heater hose clips off near the firewall . hard to get to and they had been put on at the factory with the prongs facing upwards , GRRRRRR!
the whole job took me 5 hours and so far i think its fixed my fogging windshield problem .....crossing fingers anyway .
dont know how much a dealer or shop would have charged for this but probably not cheap .
