quicksilver Posted December 21, 2010 Share Posted December 21, 2010 Seem to be having a problems with the heaters in the car going hot and then back to cold. The blowers move to all positions and work fine but just keep going from hot back to cold!!! Doe's the Z have some kind of sensor that regulates and maintains the cars temp? I'm not sure where to start looking but if anyones had a similar problem with a solution it would be good to know. Cheers Matt Quote Link to comment Share on other sites More sharing options...
Ekona Posted December 21, 2010 Share Posted December 21, 2010 Check your coolant levels. Quote Link to comment Share on other sites More sharing options...
Tarmac@TarmacSportz Posted December 21, 2010 Share Posted December 21, 2010 I had a problem with my heaters but they were permanently blowing full power. It turned out to be a loose connection of the wiring after the new gear knob was fitted. Im pretty sure there isnt a model that maintains car temperature.

quicksilver Posted December 21, 2010 Author Share Posted December 21, 2010 Check your coolant levels. forgot to say I'd checked the coolant and thats fine I wasn't sure if the car had a temp sensor that if you flicked the heating up to 30 it then regulated it to maintain a 30 degree temp, but maybe I'm talking tosh Quote Link to comment Share on other sites More sharing options...
M13KYF Posted December 21, 2010 Share Posted December 21, 2010 try taking the fan speed and position out of auto to see what it does Quote Link to comment Share on other sites More sharing options...

It turned out to be a loose connection of the wiring after the new gear knob was fitted. Im pretty sure there isnt a model that maintains car temperature. Eh.... is that not just "auto" ?

webbtay Posted December 21, 2010 Share Posted December 21, 2010 On a related note, how long does the average Z take to heat up? Mine takes ages - about 5 minutes at a minimum to get reasonably warm (if i leave everything on auto and set the temp to 25). Does it have a proper heater or does it have to wait for the engine to heat up first? Quote Link to comment Share on other sites More sharing options...

Does it have a proper heater or does it have to wait for the engine to heat up first? 5 minutes is pretty quick in these conditions. But it doesn rely on the engine getting some temparture in it beofre hot air starts to blow. In my old car (a 1.8T) it took at least 10 minutes to start blowing warm air in sub zero temperatures.

Nope - It was full blast when it was in the off position too.... red hot day and the blowers were stuck on full power/full heat..... I lost about a stone in sweat on the journey to work Quote Link to comment Share on other sites More sharing options...

dunkster Posted December 21, 2010 Share Posted December 21, 2010 ive got a very similar problem with mine, even at working temperature the blowers blow cold when sat at idle. Once i go above 2 grand it heats up, any ideas? Quote Link to comment Share on other sites More sharing options...
