I have removed fuse a2 and 2 relays and drl still work I am wodering if there is any other canadian cars who have same problem?

I was going to snip brown wire since this may be my only option on my car but I was told I will get code pop up

dadaroo

I think I saw a previous Thread you did on this. If you pulled fuse 2 in the engine box AND DRL relays 38 and 40 the DRLs should not work, even on Export cars. Of course this assumes the OEM wiring design.

What Brown wire are you talking about?

1999C5JSS

blue for Turn Signal,
brown for parking lights
ground.

if I cut the brown this will cancel the parking lights but wondering on what code will pop up on display

dadaroo

Why would you cut the parking light circuit if your issue is with the DRLs? You can cut the Brown wire if you want to, it will cause no codes.

I don't know who modified your wiring but the way it should work is the Multifunction switch turn signal power goes thru the DRL relays. So pulling the relay should prevent the turn signals from working.



When DRLs are requested (relay coils energized) power is from fuse 2 and thru the DRL relays. Anytime a turn signal is used the appropriate relay coil is deenergized.


Isn't it about time you started looking at the wiring going into the bulbs and try to tell me what you see?

1999C5JSS

by the way thanks for helping me out

dadaroo

Glad to help, there is a reason, we just need to figure it out.

OK, do you have 3 bulbs in the left and right which is Export or just 2 bulbs in Domestics?

In the Domestics the DRL and the Turn signal are the same filament and the Parking light filament is the other one in the same shared bulb. The side marker light being the other bulb. Therefore only 2 bulbs.

In either case of Export or Domestic the DRL/Turn signal wires are the Light Blue and Dark Blue, forget which color is on what side, not at home now. The Parking light and side marker are Brown also in both cases.

If we need to discuss on the phone just PM me.

Mr. Sam

PS: Do the DRLs go out at night with the headlights ON? Also, during the day, does a front turn signal cause it to blink as it should and then go back to solid bright when you turn the signal OFF?

1999C5JSS

when I first start car with ebrake on its all off. after that aways on the drl.
no matter position of the headlight switch

dadaroo

Are the DRLs interrupted when you use the turn signal?

DRL's OFF with ebrake ON is normal.

Explain what you mean by one bulb is turn only with 2 wires. (does it blink?)

1999C5JSS

sorry that was mistake.
the 2 wire bulb is parking light only not turn

dadaroo

OK, but are the DRLs interrupted when you use the turn signal?

1999C5JSS

yes what i can tell

dadaroo

OK, pull the relays out again and see if the turn signals interrupt the DRLs.

1999C5JSS

yes front turns are.

with 2 relays out drl on but no turns but rears do work stil but flash fast.

I need to fix a hole on top of lens from heat but i have plastic welder so will do that after i see how to delete drl

dadaroo

OK, something does not make sense. Are you sure you are not confusing the Parking light with the DRL?

1999C5JSS

the bulbs on left are turn and drl and bulbs on right are parking lights correct?

so with the 38 and 40 relay pulled the bulb on left of picture do not flash

dadaroo

No. The one on the left is the DRL/Turn Signal and Parking light. The one on the right is the side marker light.

The DRL and Turn Signal are one (the same) filament in the bulb and the other is the Parking light.

1999C5JSS

I guess I am lost to c5 lighting. so we know my goal here is to delete drl because of the heat issue within lens.

so if you can explain each position of the switch on a stock car so I can understand how the c5 works and when the drl works.

my plan is to have when light switch set to zero postion I do not have a running 3157 bulb. which I thought that was the point to a2 fuse or relay delete.

dadaroo

If you remove the relays you lose the DRL and turn signal function. If you remove the Fuse 2 in the engine fuse box you just delete the DRL function. It is no more difficult than that.

Do it again now you better know what lights are what.

1999C5JSS

so if the switch is off and a2 fuse is pulled then why do I still have light from the 3157 bulb? they should be off which means drl delete is working

Trios

You keep referring to fuse 'a2' but that doesn't sound right to me. You need to pull fuse number 2 in the underhood fuse box (right next to the battery).

Can you take a picture of your fuse box diagram and the fuse box itself and point out which fuse you've pulled?
