No turn signals or hazard lights - 1994 Land Rover Discovery

These vehicles were known for faulty hazard switches. They would cause an intermittent turn signal flash when you hadn't activated turn signals or they would prevent the turn signals from working at all. Operate the hazard switch and see if the turn signals work again. If so, replace the hazard switch

Do you know what a DVOM - digital volt ohmmeter is ? How to use wiring diagrams to test electrical circuits with DVOM? Do you know how the turn signals work ? What controls them ? More then likely it's a problem with turn/hazard flasher module.

Turn Signal/Hazard Lamps
The IGN E 10 A fuse in the underhood fuse block supplies battery positive voltage to the turn signal switch assembly. Ground for the hazard switch is from G302. The FLASHER 15 A fuse in the underhood fuse block supplies battery positive voltage to the turn/hazard flasher module. When the turn signal switch is placed in either the left or right position, a voltage signal is completed from the turn signal switch to the turn/hazard flasher module. When the hazard flasher switch is activated, a ground signal is completed from the hazard switch to the turn/hazard flasher module. The turn/hazard flasher module then sends an on-off voltage signal to the appropriate turn signal lamps, or to all turn signal lamps for hazard operation through these fuses:

What fuse are you pulling ?

Hazard Lamps
The hazard warning switch is part of the turn signal switch. The turn signal switch receives battery voltage at all times through the HAZARD SWITCH Fuse. When the hazard switch is placed in the HAZARD position, battery voltage is applied to the hazard lamp/turn signal lamp flasher. The hazard lamp/turn signal lamp flasher sends a turn signal flasher signal to the turn signal switch. The turn signal switch provides all of the turn lamps and turn indicators with the turn signal flasher signal, simultaneously flashing them on and off.

Turn Signal Lamps
The front turn signal lamps are made up of the front park/turn signal lamps and rear turn signal lamps. The front turn signal lamps flash with the rear turn signal lamps when a turn is initiated using the turn signal/multifunction lever. The turn signals will operate only with the ignition switch in the RUN position and will not operate during hazard flasher operation.
When the ignition is turned to the RUN position, battery voltage is supplied to the TURN SIGNAL Fuse. Battery voltage is then applied through the turn signal fuse circuit to the turn signal switch. When the turn signal switch is placed in the LH or RH position, voltage is supplied to the hazard lamp/turn signal lamp flasher. The hazard lamp/turn signal lamp flasher supplies a turn signal flasher signal to the turn signal switch. With the turn signal switch in the LH or RH position the corresponding turn signal indicator, rear turn signal, and front turn signal receive the turn signal switch signal and will flash. The front turn signals receive the turn signal switch signal from the turn signal switch via the BCM. The turn lamps are permanently grounded.

Replace the turn signal switch. Refer to Multifunction, Turn Signal, and Hazard Switch Replacement - On Vehicle in Steering Wheel and Column - Tilt.

First off operate the hazard switch many times. The contacts in the switch corrode through lack of use and this will clean them. As the turn signals and hazard lights share the turn signal unit it may be faulty.

lol sounds like my old truck most likely crossed wires

Yes, the problem is the turn signal flasher is defective. You can has two flasher relays. One for the turn signals and one for the hazard lights. That is why the hazard lights flash and the turn signals do not. Replace the turn signal flasher relay located on the drivers side of the steering column, mounted behind the instrument cluster in the convenience center. They are both mounted in the same location so turn on the hazard lights and the one that you put your finger on that is not clicking is the turn signal relay.

it could be duel filament bulb that is blown and shorting inside the bulb to the other circuit, you may need to remove all indicator and hazard bulbs and check. I would also try a new flasher can

Suggest you change hazard flasher 'can' first, then go to the hazard switch. I'm betting it's the flasher can.
