[quote:a02517bfdf="ftediously"]Heater problem
1994 Buick Lesabre 6 cyl Front Wheel Drive Automatic 100000 miles
----------------------------------------------------------------
My heater blows, but the heat is luke warm, at best.
I notices that my temperature is reading about 140 degrees. I bought T-stat, but have not put it in yet, I just put one in a week ago that was good for 180 degrees . The auto store said I should put a 195 degree one in. I wasn't working well even before I put the ne 180 degree T-Stat, so I am moderatle optimistic that this will work. Any help would be appreciated.[/quote:a02517bfdf]


put the 195 degree in and flush heater core
remove two heater hoses run water and comp. air if possible

flushed core and changed antifreeze, put 195 degree T-Stat in and still have warm air on driver side and cool air on passenger side.

Checked the doors behaind the glove compartment they seemed to be working OK.
