Have the charging system checked out. The battery,alternator,and starter.Also if all of this checks out you may have a battery draw(something draining the battery). If you use your car every day it will never show up.

The fan motors keeps running after car is shut off. Also sometimes fans start when car is started cold.


If the fans didn't run any further the engine continues to warm and possible seizure will occur. This is also the reason you will probably go through batteries in the long run. Hopefully this helps the issue you are having.

Heater blows cold air


With the car warmed up,feel the heater hoses,are they both warm/hot near the firewall in the engine compartment?If they are both warm/hot,then the heater core should have circulation through it and it may be a "blend door" issue in the heater a/c assembly.If they are not warm/hot then the heater core could be dirty and plugged up and needs to be flushed.
If the above does not help,a drain and vacuum of the cooling system and vacuum refill will remove any trapped air.
Sometimes,clamping off the top rad hose and holding the engine rpm at 2000 rpm will force trapped air out of the heater core.(Watch temp gauge when trying this)
Lastly,a NEW thermostat doesn't mean its working correctly.
