Question about 1987 Nissan 300ZX
My 87 300zx 5speed manual is very nice except no heat, cold air only. It has the climate control system and even the defrost is cold. It says demist/defrost and both selections give out only cold air. Help please. Thanks, Daniel
Begin by warming up engine. The from under the hood hold both heater hoses to confirm that heater core is getting hot water. If hoses are not hot then the fault is likely to be the thermostat stuck in the open position. If hoses are hot, then you must access the heater box, behind the glove box. there is a blend door which must move from cold to hot. Check this and keep me posted.
