Chevrolet: My celebritys heater is not working, heater hoses, rad cap

Question
my 1989 celebrity just recently started this problem. I'm in the snow belt of West P.A. so I really need my heat to work. If you could tell me what the possible problems could be, that would be a blessing..Thank you in advance..

Sincerely,
Willie

Willie;
Hi; well it could be a few things.I would check all of the hoses, and the rad. cap. and flush the system if it is  dirty. but it could be the heater core, or the heat control valve,if one of the heater hoses gets hot and the other one stays cold, than its the valve if it has one on it or the heater core. and how is the thermastat.   ok check all of those things..
