One or more of:

1. Your coolant level is low
2. Your thermostat doesn't close and needs to be replaced
3. The valve from the cooling system to the heater core is stuck
4. Your heater core is clogged

2000 Lesabre has very little heat from heater


A common cause of slow heater warmup is a bad radiator thermostat. It's cheap and easy to replace and you ought to replace it every three years or so on general principles anyway. So change that and see if it works.

When I lived in a snowy area, I put a newspaper in front of my radiator to get it to warm up faster for local trips. I took it out en route for long trips.

Someone please help!!!! I have a 2000 buick


A cam sensor only helps the computer when cranking and should not make it cut off. Most cam sensors do not go bad, but he magnet on the timing gear will deterorate. To fix that the timing cover will have to come off. Replace the crank sensor they get hot and stop working. When they cool down they will work again until it gets hot.

NO HEAT 2000 buick lesabre


If this Buick has a 3.8L, there are air bleed valves that must be opened to ensure the cooling system does not develop an air lock. (Wich would cause a no heat condition). If the thermostat is functioning properly you may want to check if there is flow through the heater core. Check by feeling each heater hose at the firewall with engine at opperating temp. They should both be hot and close in temp. A noticable temp difference in the two hoses would most likely be a flow problem, either from an air lock, bad t-stat or plugged heater core. Good luck.
