DRLs turn off when AC is on!! Help!!

Bit of a weird issue; thoughts most welcome.

I've had JW Speaker Evo 2 DRL LED lights fitted (also WIPAC LEDs all round) by TMD. Nice and neat job.

I then had the MUD side mirror defroster kit fitted (wired to use the windscreen defroster switch) along with a Pioneer powered subwoofer by Auto Audio UK. Again, a nice and neat job.

After all the work was done, I've noticed the DRLs turn off every time I switch on the AC (on my 2015 90XS). I thought maybe the battery is weak, but after two days of solid driving and also trying on the front or rear defrosters, the DRLs work fine except when the AC is on.

Anyone have any similar experiences?! TMD have never heard of it, nor has the importer of the lights. I'm off to Auto Audio UK later to see if they can find a reason for this happening. Google didn't find anything either.

Thoughts most welcomed!

Cheers,

Edzi

Which DRL controller do you have? Some only have a 12V feed from the battery, and switch the DRL´s on when the input voltage goes up to over 13.4V. In other words when the alternater is charging (motor running).

Do your DRL´s switch on with the ignition, or only when the ignition is on AND the motor is running?

If so, then it could be that, at the point where the DRL controller is connected, the the AC is pulling the voltage down below the switching voltage.

Connect the DRL controller directly to the battery +. Check the controller´s earth connection, too. 1998 Tdi 90 SW,

Many thanks for the suggestions. I'm sadly not technically minded, but will check all this when at the garage and also run it by TMD. I don't recall if the motor is running when the DRLs come on - shall check when in the car next.

These are the exact units:

Much appreciated

Do the DLRs work correctly when the headlights are put on (I think they should go out but may just dim). Thought process is maybe a feed has accidentally been taken from the a/c supply rather than the lighting to turn them off? 2003 Defender TD5 Hardtop (current - work in progress)

They stay on but I think are dimmed. I'm only judging this by the reflection I've seen whilst driving. Shall have a look later to see properly. Thanks

Ok, had a look. The DRLs come on when the ignition is in position one (radio comes on etc) and stay on when in position two and the engine is running.

Edzi,
I have the same EVO II´s fitted to mine. They came with a controller which may well be the same as yours. It has a permanent 12V input and an igniton switched one.

It is the ignition switched one which actually decides when the DRL´s go on, and judging from the fact that the DRL´s go on with the ignition, would appear to be connected correctly.

A third input from the side lights switches them off - when the side or headlights are switched on.

Could you check to see if the DRL´s are switching off when the side or headlights are activated? Do they dim or do they switch off completely? 1998 Tdi 90 SW,

Thanks for your reply

With the side lights, they dim but remain on.

If the DRL´s switch on with the ignition and switch off (or dim) as they should do with the side lights, it would appear that the controller is still correctly connected.

And it means I´ve run out of ideas how to help you, I´m afraid.

Anyone else got a suggestion?

Your best bet is to bring it back to those who last worked on it. But I´m sure you´ve already thought of that.

Good luck! 1998 Tdi 90 SW,

Thanks

I was at Auto Audio UK and they looked at it and said it wasn't wired up properly. They re-wired it and it now works perfectly. TMD which installed it are over 2 hours drive, so glad I could get it done closer to home!

Thanks again for everyone's suggestions

Update: TMD to their credit will be refunding half the labour they charged and also contacting other customers to make sure the wiring has been done correctly.
