Hello and welcoe to JustAnswer!

If the flasher and switch have been replaced and fuses are good then you either have a wiring issue or multiple blown bulbs. Have the bulbs been checked or replaced?

Customer: replied 7 months ago.
the bulbs have been replaced. I m sure you are aware Land Rover has no flasher, per say, only flasher relays for each side.
Customer: replied 7 months ago.
I asked for specific information, detailed to vehicle specific. Haven't seen that so far.
Expert:  sprinkles08 replied 7 months ago.

There are two turn signal flashers in the box in the dash.

Have you used an incandescent test light to see whether it's power or ground you're missing at the bulbs?

Customer: replied 7 months ago.
No sir, I ve just replaced the bulbs, turn signal switch and flashed relays.
Customer: replied 7 months ago.
I can check that, but I m pretty sure it's power that is missing .... Which way to go after checking for either of those?
Customer: replied 7 months ago.
I m leaning towards a becm problem, but I d like to make sure. The repeated chattering of the left side flasher relay every 15 seconds(appx) has me baffled though.
Expert:  sprinkles08 replied 7 months ago.

Either way if the bulbs are good, the flasher and switch are good and the fuse isn't blown then the problem is wiring. You'll need to first determine whether it's power or ground that you're missing and test from there. It's possible that you could have a poor ground to the lights, voltage drop or an open circuit between the flasher and lights. A short to ground is also a possibility but should blow the fuse.

Any way to determine a BeCM problem?
Expert:  sprinkles08 replied 7 months ago.

The body controller? A scan tool would need to be used to diagnose an issue with the BCM. A scan tool could be used to check switch input, check for fault codes for the output circuit and perform actuator tests.
