Heated Windscreen Question

[JDF]

Hi All,

 

I hope someone could please help me out here, I've had a quick look on the "search" but couldn't find my problem?

 

The front heated screen our Mk I Galaxy seems to be playing up.

Are they external temperature sensitive?

The reason I ask is, our wont switch on unless it is very cold i.e. Press the switch and it lights up, but go's out again after a second or two.

Even when there is ice on the windscreen; it doesn't want to stay on for very long before it switches itself off, sometimes it doesn't stay on long enough to melt the ice.

 

I'm sure this is not correct?

 

Can you suggest what might be wrong & what I should be checking/replacing?

 

Cheers in advance.....

Sounds like a faulty switch to me. Does the relay in the fuse box click when you operate the switch?

Thanks for your help "Beyond Help?",

 

I'm pretty sure that the relay does click, but it turns itself off so quickly its difficult to tell.

Do you know which relay/number it is?

Just so I know where to put my ear when I try the switch again.

Will have a play this evening.....

 

If the relay does work okay (if only briefly), you think it might be a knackered switch - does it have the timer built into it then?

 

Cheers

The relay contains the timer so it's probably this that needs replacing.

Thanks "insider".

You don't happen to know which relay it is & where it is located on a Mk I?

Cheers

I had a quick look for relay #22, but can't see it on our MK1 inside the drop down fuse cover.

Can see a number of relays 30, 21 etc but no 22.

Is there a hidden layer of relays like on the MkII?

I can hear a relay click in on activation of the switch, but can't make out which one is making the noise???

Please help !!!!!

On your car the H/W relay is number k164 in the following diagram, its behind the main relay panel:

Hi MadBaz,

This is probably a dumb question, but how do you get too the panel behind the main relay/fuse panel?

I didn't know there was a further panel on a MKI !!!

 

chazy,

I haven't checked the earth lead yet, although it must be conected as the heated screen works okay the 1st time you activate it, but if you try to turn it on a second time (eg if it's not quite cleared the ice) then it only comes on for a few seconds before it switches itself off again. Therefore I think its the timer in the relay thats not working properly....

 

Cheers for your help....

HI

im sure theres an easyer way but when i had to get to the second layer i removed the lower trim under the stearing wheel then i think there is a screw at the top of the fusebox in the center attaching it to a curved metal bracket then just the two white clips at the bottom then a bit of wiggling and pushing up to release it once out its easy to unclip the two sections to get to the second layer.
