Title: Cruise and aircon - problem - not working / only h
Post by: Paul on 30 December 2007, 09:37:58
1. I dont know why my Cruise is not workinh. Nothing going on when Im pressing any of 3 buttons at all. Checked fuses and averythink seems to be OK (fuse No 15). Any ideas?

2. my aircon is only blowing hot, doesnt matter what settings im using. Do i just need to recharge it? I heard both pipes for cold and hot air are connected..

 :-?

If your cruise control used to work and then stopped, it's worth investigating the stop lamps. I've had poor bulbs cause this once.

Brake switch is the favourite for cruise problems....

As for only blowing hot....do you have aircon or climate?

Climate (I think..)  ::)

My brake bulbs are OK.. Brake switch? Brakes are working as they should.. Where that switch is located? And how to check it? Only replacement?

Ok....when the climate turns off......do you get a set of dashes displayed in the temp displays?

Has the panel been removed to replace bulbs recently?

Do the controls for air direction work (i.e. screen, face, feet)?

Yes, everything works, no dashes etc. Fan speed / direction etc works. Id only does not blow with cold air at all.

Panel never removed..

And noticed one more think - maybe only bulb - but my ECO button is  not working..

When turned off, there is nothing there. When turned on I can chcnge tem from LO to HI no problems.

After I will switch it off ive got dashes for 2 secs, but I think its normal.

Where cruise is fitted there is a 4 pin brake switch.  one circuit for the brake lights and the other for the cruise circuit.  If this second circuit fails the cruise will not work.

If you want to check the electrical feed to the cruise module, see the link below, gives my pin readouts from the cruise multiplug.  If you can replicate these then you do not have an electrical problem: move on to the actuator itself or the cable.  If you cannot replicate then I'd suspect the electrical feed to the unit, depending on what you find it may be the brake, clutch or even the cruise stalk itself.

That means the panel is complaining about something....

Hmm.. I had the same on my MV6, but it was OK.. Let me take a closer look again.. Will be back soon! :)

Update:

as you can see everything seems to be OK.. Dashes at the very end are shown onlyu when Im turning ignition off with aircon off, so I think its OK.. Is it?

The dashes indicate that there is a fault code stored....

Noticed from your Pic's you have a manual, so your also have Clutch Switch to check as well.

Doen't the manual also need to be in gear for the cruise to work, so must be some sensors there as well, not sure about that one?

never tried my cruise in Netural, but never thought to, it has no power in N so can't see it engaging.

On a manual, putting it into neutral without pressing the clutch does NOT dis-engage cruise.....try it....the engine revs start to creep up and up...
