R32 - Heating Not Working

[abu]

Hey

Just picked up my R32 today, more than happy with it.. but the heating doesn't work, and it is winter at the moment!..

The fan and all the different modes work, like feet, face, and fan speed, 1,2,3,4 etc

A/C works and all that other stuff, but no heat, it just blows cold air.

Any ideas what it would be, I got no idea and don't know where to start looking.

Any help would be appreciated.

Thanks in advance,

Abu

Hey mate, I recently had the same problems your getting. First of all, try holding down the heat button for about 10sec or until an sign 'FH' appears on the screen. It should overide all the sensors and push out as much hot air as it can. Make sure the engine is warm too. Give that a try and if it still doesn't work then I think it could be something to do with the motor which controls your hot/cold air.

Let me know.

Hey man

Thanks for the info.

When I held down the heat button the FH symbol did come up but not hot air came through the vents, stillt he same cold air.

Car was warm, and I left it on for a while in FH mode, but still didnt work..

Will look into it further on the weekend when I get some more time.

Any one have any more information or past experiences with this?

Thanks,

Abu

Sounds like you have the same problem I had. Try doing the diagnosis to see if there are any other problems. Shouldn't take long and it'll show you what's wrong. If not, it SHOULD be the problem I was having.

This link should show you how to diagnose your system.

As Adam said, it sounds like the motor controlling the door which controls the blend of hot and cold air. i was having the same issue, so i pulled the dash out and made the easy diagnosis. I Replaced the motor with a second hand one and now i dont freeze on the way to work in the morning. Feel free to pm me if you need a hand.

Damn, you had a hard job of fixing it didn't you. All I had to do to fix mine was shake bits of cable where the motor was.

Thanks heaps Adam, I will read through that thread and see if I can work it out. Hope its nothing major, i really like the heater lol

Especially at this time of the year!

Damn dash out!! Stuff that, I hope its not that serious.

I will see how I go with the diagnosis and then go from there. Thanks for the offer of PMing you if I have any issues, will definitely take you up on that!

Thanks,

I think you can replace the door motor but just removing the centre consol section where the stereo is, but if it ends up that the motor isnt the issue you will probably have to take the dash out anyway to work out where the issue is. The dash out job is pretty easy anyway once you have done it before.

Are you sure you have to take the dash out to replace the motor though? I remember when I was stuffing around with the motor to try and get it fixed, it didn't seem to hard for it to get out from where the passanger's feet go.

How long did it take you to remove the dash R324DR? I hear it's about 6 hours!

Go on to Page 3 of this "General Maintenance" subject, and there's the same subject ( about 20 posts, I think)... May help, and shortcut doing it all again. Have you tested it after a reasonable distance. Takes a while for hot warer to circulate thru heater radiator.

Hey

Thanks for that, will check that thread now.

Yep, done it over a fair distance, tried it over 30kms of driving lol

like is said, i think you can replace the blend motor by just taking out the centre consol part (sterio, ash tray, climate control unit, gauges (if GTR), plus side sections). If your in a hurry the dash should only take about half an hour to an hour to take out. Will take longer if you have no experience with removing car interiours, but no where near 6 hours.

[adam-__-]

Oh okay, so about an hour max if you know what you're doing. I remember seeing 'how to' thread about removing the dash and they said about 6 hours.

make sure the heater isnt bypassed in the engine bay, this can be done when the heater core starts leaking.

Thanks man. Checked that one already

Will bleed the cooling system as well, might be an airlock in there causing the heating not to work.

Got some free time today so will run the climate control in that diagnostic mode and see what it brings up in the error table!

Thanks,
