Car is running hot and have no heat why?

(1999 Oldsmobile Intrigue)
in Piggott, AR on February 27, 2015
I have a 99 Oldsmobile intrigue and I had water in my floor board the other morning and it was running hot so I replaced the heater core yesterday and drive it about 10 miles it seem to be alright then it started running a little hot and the blower kicked down on its own then back up again but was blowing cold air then instead of hot, so a little bit ago I changed the thermostat and its still running hot and no heat? What could be the cause?

I agree with Mr. Crosby, you have an "air Lock" in the system-depending on the engine, there should be a "bleeder" somewhere close to the thermastat, if not try loosening the upper radiator hose enough to "bleed" the air out, just be careful not to burn yourself with hot water as the engine generally needs to be warm enough for the thermastat to be open and have full coolant circulation, an air bubble will have a tendency to go to the highest place in the system. Sometimes an "air lock" can be a real bugger to get out!

Most likely there's air in the system. I have a 2001 Intrigue and ran into the same problem with overheating and no heat. You probably need to bleed the air out.
