Heater not always hot

It seems that my heater is solar powered - if I try to blow hot air at night, I never get any, but can get it whenever I want during the day ...

Anybody got any ideas?
 
Rely upon global warming?

No suggestions, sorry. There are various problems (documented on here) about heater control arms coming unclipped and then not activating the vents as they should, but this wouldn't be affected by day/night.

Are you sure you are leaving enough time for it all to warm up? I don't get hot air for a good 10 minutes after a cold start.

Are you still not getting hot air when the temp knob it turned to fully hot? The system on our cars is basically climate control and the system will try to maintain the temp set by the temp knob - but the cooling capability of the system is limited to the temp of the ambient air unless you have A/C. But if you turn the knob all the way round to the red dot you should get hot air all the time. If you are not getting hot air then you might have a problem.

I think that is only on certain models/dates or an optional extra?

Mine don't have sensors............look under the little grill on the dash (post 85)

I was under the impression that certainly the oval dash models had this system. The little round grill thing to the left hand side of the LCD clock is the temp sensor for the system and I know that the temp varies out of my system even when the A/C is off. All the A/C button does is provide the ability of the system to mix the air with chilled air to better control the temp.
 
All oval dash models have the grill, mine has no sensor behind it.

It might be because it does not have A/C.......and no degrees on the control.

IIRC the degrees indicate you have climate control.........Don't know if all A/C options have this?

Some oval dash cars had the blue/red scale on the knob. Only the cars with numbers use the grill and keep a constant temp.

The problem the post is about will be due to broken clip I expect. It has nothing to do with day/night and everything to do with the ambient air temp being used as the cold air in the blend fed to the cabin.
 
OK, the temperature knob has the numbers on it, and the car has AC, so I took this to mean I had climate control.

Regardless, no hot air at night, no matter how long or short the journey. Plenty of hot air during the day, but as was pointed out, I don't drive with lights on during the day. How does does having my lights on affect the heating?

And somebody mentioned a broken clip? What clip, and where do I look?

It shouldn't, but what else do you do differently at night [;)]

Broken clips normally default to full heat, it is designed that way so the more easterly Europeans don't freeze to death [:eek:]

The only time my clip broke the car did weird things, not default to hot. For me it would go hot under acceleration and cold under braking (or maybe vice cersa).

Take out the glove box liner for access and the clip holds two linkage rods next to the centre of the dash. It's so cheap I'd just replace it anyway while you're in there even if it turns out to be intact. If it isn't the clip other things to check are that there is no lint blocking the bulkhead end of the temp sensor hose, that the hose is connected to the vent in the dash and that the vacuum line that controls the flaps in the scuttle is connected and doesn't have any holes or crimps in it.
