Strange problem and could do with some help please.

Drove to work this morning approx. 30miles..A/C working fine and nice gentle cool air from blowers.

Parked up in direct sunlight for around 2 hours..got back into car started fine but felt warmer than temp at 20c climate panel was showing.Pressed blower to increase speed but no improvement.Turned climate down to increase cooling but still no improvement and no blower.

Checked A/C and clutch engaging and when moving there was a definite cool air movement but blower wouldn't work on ant temp setting nor manually adjusting with either eco on or off.

Have checked all fuses under steering wheel as seems several are labelled cooling fan but non are blown and everything else electrical seems to work.

Would of expected if motor failed fuse to of blown so now struggling to thing what else could be the issue.Assume there is a relay in the circuit...any idea which/colour and where .

Any help appreciated

Drive with windows and roof open for a spell, close up and try again.

I did on the way home as it was fek..in hot but no improvement.

Car now parked up on driveway..all fuses checked but it still wont fire into life

[Doctor Gollum]

Ho hum, only suggested as if the interior temp is too high, it can struggle to make a difference 

Pollen filter dry

Either the panel is goosed or the hedgehog... Which is up to you, but the hedgehog standard failure mode is full power or nothing*...

*try resetting the panel

[amba]

Tried a reset but no improvement ,but can hear servos churning.

Climate panel allowing the alteration of the air from face/screen etc so power is getting to that and functioning correctly.


Hedgehog replaced last year and never had any water inside so strange if that is the fault but possible I suppose.

Are there any relays anywhere under the bonnet etc that could be influenecing this ?

[Doctor Gollum]

Don't think so... Be the dash fuse panel, probably a 30/40 amp maxi fuse... There's 3 there iirc, one for the blower, one for the rear screen and one for the windows... 

[amba]

Pulled every fuse inside car and non have blown.Even swopped those which say for blower with 1 from another location with same rating and still blower will not respond.

My thinking now is the hedgehog as that controls the fan speed so if its totally dead now circuit is getting to fan.From past problems with fans they tend to make a noise before either dying or running erratically.

Looks like the glove box etc is coming out tomorrow now as cant cope with no cooling in car ,and will see what I can find and check.

Assume there is no diagnosis for hedgehog .??.but fan can have 12 volts put across to check.

Now to source a supplier

[Doctor Gollum]

If fan only runs at low speed it's unlikely to be hedgehog...

No fan at all suggests a control issue, which is the panel...

[amba]

No fan speed at any setting so either panel or hedgehog then ?

Is there any way of diagnosing which

[Doctor Gollum]

My money is on the panel...

Have a spare here, but unless you can collect it from Gatwick as I fly out tomorrow, I cannot be of much more use

[amba]

Thanks for the kind offer Al,but am heading towards Canterbury so opposite direction.

Have a good flight and thanks for advise

[Doctor Gollum]

 

Hopefully you'll get it sorted easily enough

[amba]

My thought is still with the hedgehog as the fan speed indicator is registering on the climate panel,all air diverting buttons are prompting the servos to sound and logic seems to be a dead short in the resistor.

Think for around £20 will take a punt at a new hedgehog and go from there
