94 deville heater problems cold on left & hot on right side ????

Heater blows equal amounts of air on both sides, but passenger side is hot and driver side is cold. This car doesn't have dual climate control. The temperature control is set on 90... Thanks

just did mine. it does take a little time, and you have to look at every way possible to get the parts back in. but it wasn't too bad. i had a pontiac that you had to cut a hole in the inner fender to get to a couple of bolts. the caddy was alot easier than that.

The reason it is the heater core is that it has a upper and a lower portion the upper feeds the passenger seat and the lower feeds the drivers seat area. Do it yourself it cost me 350.00 at garage
