my 1994 deville was the opposite - warmish on passenger side defrost and cool on drivers side. Turned out to be a problem with an inexpensive plastic " T " that (on my car) is top and center near firewall under the hood. too much hot water was going thru the bottom of the T and not enough going thru firewall to heater core. $20.00 part fixed it!
