1999 Corolla hazzard lights not working. Indicator's are, but only if hazzard switch is off?

Short term, pull the drl fuse, see if lights go out. Check to see if headlamps will still work with drl fuse removed? If they still work, don't worry about it.
Just between me and you, I've never cared for drl.
I can give you wiring diagrams if you want?

check for any blown bulb or fuse

As for the brake lights push brake pedal down while pushing on and wiggling the hazard switch.If the brake lights come on then replace the multi-function switch.

I think there are 2 fuses for those switches. Fuse #11 & #39

Hope that works for you

Hi, you might have a problem with the indicator switch. You will need to make sure that there is power into the switch and power going out of the switch. If you do not get any power into the switch it might be that the fuse is blown. If there is power into the switch but not out the switch is faulty. If there is power in and out of the switch you will have to see if you get power on the indicator globe connections. If there is no power there a wire might be broken, but I think your problem is with the indicator switch.

It could be the brake light switch above the brake pedal. Maybe this switch is bad. Just another thing you might want to check.

need more info ??does it work with hazzards on ??all four lights?'

the relays could have been screwed or have snap off locks, be patient enough to get it off then replace it!

or you can maybe check if the connector is still in place, you can open the mounting around the vent, radio and hazzard button, the plug for all flasher is under check if it still plug first...

I respectfully disagree with the post by C17Hydro.

The turn signal flasher relay is under the DASH, on the left side of the main fusebox; it is not under the hood.
