Relays!

[Fassy]

Hi all,just found this site an hour ago.I'm a bit internet illiterate,forgive me.

On my IS 200 sport Y plate my wife left the interior light on,and flattened battery(it was on the way out).When I came to the car the headlighs were on and a buzzing sound,(I had the keys in my hand).The sound was the headlight relay!I fitted a new Battery and a new relay,drove 30 miles,came home and looked out window and blow me down the damm lights were on again and the new relay buzzing!!!Any thougts out there what it could be?

Hi and welcome to the LOC don't think i can answer your question sorry but i'm sure the lads will help out very soon

What do you mean by buzzing relay????? my pennies worth would be to reset the ECU although disconnecting the Battery should have done this anyway.....

Sounds as lf you might have a bit of moisture in the Relay, the same sort of thing happened to my old Scorpio.

Welcome to the club

Cheers Peter,how did u fix it??

Try some WD40 as it will evapourate the moisture from the contacts.

Hi - I'm new to the forum? Have you checked the voltage getting to the relay? A bad cable, corroded connection or a bad earth connection could drop the voltage which is likely to make the relay unhappy.

This sounds like a know issue on early IS200s

Have a look at this old thread:

If you can get the unit in your hand take it to the garage and blow some comp air into it and dry the end of the fuses/relays at home with a rag.

Well today I looked at the fuse box in the drivers footwell and its as dry as a bone.Then I took off the rubbers and plastic cowling below window and the drain holes were full of crap,and was duly cleaned.One question,what is the 3 sensor looking wires underneath the window?I thought it was to do with the auto lights but obviously not as I disconnected it and the lights still worked.Came home and the lights mysteriously came on again within 20 mins!!!!!!!!!!!!!!!!!HELP.
