If they don't blink when arming/disarming Tony, the problem is almost certainly that you have higher wattage incandescents in the Turn Signals (there is a note in the install guide that you cannot fit more than the std 10W bulbs)
(I run into this all the time with the UK guys particularly, where the clear lens/orange bulb mod is quite popular)
It's not 'broken', the drivers simply current-limit when they are 'asked' to drive higher current than the designed 10+10 watts.
You can test this by simply disconnecting your front (or rear) turns and if it works to flash the other end still connected, this confirms the issue.
The solution will be to either go back to OEM rated 10W bulbs, or perhaps better, install LED bulbs (in which case you will also need an LED-friendly relay)
In actual fact, you can probably get away with just changing to LEDs at the front ONLY, leave the 20's in the rear and it should flash at normal rate with the std flasher relay
This is the note in the installation guide:
