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

Re: can't get any heat at all.
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.

If you have owners manual check that your climate control settings are as you expect them to be, if that makes sense. Some on Fixya do not realise they gave climate control , they think they have normal A/C and try to correct chimerical problems. Please check and repost
No this shouldn't affect the heat on your climate control, as the air-con is a separate entity the heat is transferred from the engine, but the air-con cold is a complete unit on its own so should not affect heating the car, just cooling it inside. hope that helps
I have a 2000 pontiac grand prix with a digital climate control system.
The heat quit working, it doesn't blow out any heat. Now that it is warm
outside the air stopped blowing out any air. The digital temperature on
the climate control is not correct. When it states that it is below 30
degrees on the ext and it is warm outside the air wont be cold. Once it
starts going above 30 degrees the air gets colder. Today the blower stop
working all together. Was told it maybe the climate control unit was
bad. You can hear the door opening/shutting when you switch the temp
from cold to hot. But there was no heat blowing out whatsoever in the
winter time. Could you please give me your opinion on whether or not it
is the climate control unit or something else?
the main issue with this is either the thermostat or the climate control switch I do not know if your climate control switch is electronic or manual either way I would start out with the cheapest and go with the thermostat first good luck!
I have checked every site that I can think of and run the question many times, unable to get the procedure, maybe a nice tech at the local dealer will help u out, if not I guess buying a service manual might be your only option. I am a retired Ford mechanic, I did almost all the AC work, I never found this problem was a control head issue, it was always the blend door electric motor, I think you can see it from the glove box if you remove the liner.
