How to bypass Hazard Switch (to keep your turn signals)

Recently had to pull my NAS hazard switch, and I know many in the past have experienced issues with this switch itself (it seems to be a common failure point these days).

Anyhow, I figured out how to "jump" the switch once it's removed so you can retain your left & right turn signal functions using the indicator lever/stalk on the steering column. Essentially, what you have to do is jump the 2 bottom female terminals (as seen in the 2nd photo) on the hazard wiring harness...and voila, you have turn signals again!

This was plaguing me while I worked on my switch as I don't like to drive without turn signals, so grabbed the multimeter and set to work.

Hope this helps someone else as well...

My hazards and my turn signals don't work, symptoms just like Jason described. I tried his jumper, but it didn't work. All the fuses in the box behind the shifter are fine.

Any other ideas that you guys can suggest?

Did you check the turn signal stalk/switch?

Flasher relay would be my starting point. Relays are switches and the contact points burn.
Once had an issue where nothing worked on my 110 and the flasher relay was full of water, small price to pay for being able to drive through 5 feet of flowing water.

Where's the Flasher Relay?

I'm doubtful that it's the turn signal stalk.

Mine (1984) is behind the fuses, inside the panel in front of the shifter. I think in newer models, which use more relays, they put some relays behind the instrument panel (in front of driver).

Signal flasher on my 97 110 300tdi 3door is behind the instrument panel....i just came upstairs, could have taken a pic for you, can still do tomorrow.

It might be the flashing unit indeed, but check fuse too, if blown..check for short before replacing.

My 89 CSW 200tdi had it within the fuse/relay compartment.... yours might be behind the instrument cluster, I will be relocating mine for easy access.

Jason, fyi if you present the vehicle for state inspection in va and if the inspector is doing his job not just licking and sticking, you will fail state if hazards do not work.
not bursting your bubble, just a heads up...

Not bursting my bubble, this original thread was meant to be a "temporary" or on-the-road fix to a common NAS problem with its frequent hazard switch failure issue. Just to bide folks time to diagnose by either disassembling & clean/lubricate the internals of the existing switch, source a new switch (tough these days since it's NLA), or change over to the Carling Hazard setup.

My switches all work as they should, quite frankly a Rover probably requires use of its hazards more than any other vehicle .

In my situation the switch disassembly/clean/lubricate worked, but it's a finicky job. Seems like many folks swap over to the Carling ultimately (which is why I came up with the NAS to Carling Hazard Center Dash Face Plate).
