Buick LeSabre Problem Report
Buick LeSabre Heater blows only cool air...even w/ defroster on
Only the cold/cool air comes out of my unit. I have checked the control panel (removed and opened) to ensure the device was moving properly from side to side (cold to hot), it does. I then checked the battery, making sure the reset, from having my mass air flow sensor replaced didn't cause a misread to the electrical system. Today, I find it is the accualtor door. Part $91.06 plus tax, Nash Cheverolt, and $117.00 for labor. I did it myself, it was approximately 10 screws and 30 mins (or so) of laying uncomfortabley on my back.- no jokes, please. Heat works like a champ and the Buick gets to live another day in my garage. - Visitor
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? - grorrer
Heater blows cold air. Have not found a solution. - Visitor
Had the same problem. Mechanic flushed out the entire engine and cleaned out the gunk that had built up. Now I have heat after nearly 2 winters without it. Be sure to have them check all hoses and connectors after the flush out; I had a leak within 5 days from 2 elbow parts (plastic) that disintegrated because they had pretty much been held together by the gunk inside. - Visitor
