2005 Buick LeSabre Problems

Heater blows only cool air...even w/ defroster on

I'll turn up the temp on the dual control to get heat, and/or the defroster to blow warmer air. All I get is cool air that makes for an uncomfortable ride and slower defrost. I did replace the blower motor in the summer, could this have caused the problem by not hooking something up correctly?

The Fuel Pump May Fail Causing the Engine to Stall or Crank Over But Not Start

The fuel pump can fail causing the engine to stall and not restart. Our technicians highly recommend to replace your fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.

Erratic Shifting of the Automatic Transmission

The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

Bought this 2005 in 2013 with 75k on it. Avg mileage 22mpg HORRIBLE. The care this car received from the first elderly owner was impeccable and now I'm driving it minimally but see no improvement in the mileage. Hwy or city...it doesn't matter. It's HORRIBLE. Where is all the wonderfulness that I've been hearing about?? Yeh, the car is sturdy, smooth, quiet, and reliable. But it's a tank...a ga...
