Re: Heater Issue
well if the control valve is open and the hoses are getting hot then I would say its got a heater control issue under the dash.
IF the hoses are not getting hot given its age I would suggest a coolant flush. it maybe very plugged up.
secondly check the anti freeze. if the coolant is set to more then -30* it is to pure. if it does not have water mixed in the right ratio it won't absorbe heat from the engine and transfer it to the heater.
