    I have the same problem, no heat. There is a really loud click/tick in my dash. I have seen some youtube videos about blend doors being messed up, and it sounds like that. I just have no idea how to get to it. (2007 Buick LaCrosse CX)

2008 Buick LaCrosse blows cold air, changed thermostat no change


Might have a bad actuator, which open the access port for warm coolant to enter the heater core.

Blower control


Sounds like a thermostat and/ or the system is low on coolant.
Its probably not going to reach 200 degrees when the outside air temp is below freezing, but you should get plenty of heat if the system is working correctly.

2007 BUICK LACROSSE NO HEAT


How difficult is it to access the control valve? I didn't find it under the hood so I am assuming it will be under the dash. The fan is working good, and the car is coming up to temperature beautiful.

No Heat


It Sounds Like You Have Either A Faulty Heater control Valve Or On The High Side A Bad ATC (Automatic Temperature Control). Check The Hoses That Go Into The Heater Core Both Should Be Hot At Normal Operating Temp. If The Outlet side Is cold Or Luke Warm You Have A Bad HCV.

2007 Buick Lacross hearter blows only cold air


I have 2007 Lacrosse with 90,000 miles.It was doing the some thing all it was is a restricted heater core. Warm the car up to temperature, feel the heater hoses under the hood, at the fire wall if there is a big difference in temperature, it is the problem.I found it easier to take both heater hoses of at the block then run a garden hose into the one that was hottest and let the other one run into a container, Then you will see what washes out. Put them back on and add water you will have heat again, You should flush the whole system because what is happening your antifreeze is wore out. Good luck!
