First check the radiator and make sure it is full....If not fill
check your hoses that go to the heater core to see if they are leaking....Your heater core might be bad which is most likely the case.

SOURCE: Where is the heater control

It sounds like the heater control valve may be stuck. This valve allows heated water from the engine to pass through the heater core which in turn heats the inside of your car. If this valve is stuck, only a small portion of heated water will pass through. If this is the case, you should have the control valve replace.

You should be able to find it by following the heater hoses coming from the radiator leading back to the firewall. These hoses will about 1/2 - 3/4 of an inch in diameter so you shouldn't get them confused with the normal radiator hoses.

You can probably purchase a new valve at an auto parts store but I'm sure the dealer will have one.

If that's not the problem, it could be that the core itself is clogged up. That's a little more expensive and more of a pain to replace. if this is helpful please dont forget to give rateing thank you

SOURCE: how do I compress the rear brake piston on 2007

hi from uk most rear brake calipers have auto adjust mechanism and yours may be the same as on uk models whereas to compress the piston back into caliper to facilitate fitting new pads ? you have to both press and rotate piston and this sends piston back on the screw auto adjuster you will notice that piston has a couple of slots on its head ? this is there for enabling screw back having said this there is a rear caliper piston compress tool that does this job and the cheapest tool and good quality is made by draper tools and costs approx £10 in uk but can be obtained at any good auto stores and has instructions on use well worth the investment ? just one tip pistons normally screw back clockwise however! on fiats? the nearside screws anticlockwise so just observe that piston is going back when rotating c/wise if not you can fit a 3/8" drive extension and t bar to the rotator boss and using pressure ?turn piston a/clockwise hope this helps one word of advice !make sure you bleed brakes afterwards to clear out dirty fluid untill clean fluid shows this will improve brake pedal best wishes from uk

check the earth wire first,wattage on the bulbs in case their wrong or old type bulbs ,check supply voltage ,if all ok then fit aux spot lights .if still having a problem have eyes checked as over 40 the old peepers can deteriorate ,dont know the name of it but it can affect some people at a younger age than others,glasses will not correct this problem.

No heat in 2007 Lacrosse and I replaced the thermostat with a new one

If the heater hoses are getting hot, it could be a blend door problem under the dash.

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.

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!
