Turn signals work intermittently

Is your heated rear window not working either? I had the same problems - it was the multi-function relay. You can find this just behind the fusebox on the left side (standing at tthe front of the car facing the windscreen) -it's a box about 2 inches square - give it a wiggle while the indicators are on and you will probably see it sorts the problem. You can remove it and check the solder joints as well - if they are faulty you can resolder. Quick squirt of wd40 on the contacts helped too. Problem all sorted now.

Is the wiper delay switch and the turn signal on the same stalk? If so, check the ground wires for the switches, otherwise the switch may be failing.

Mine does the same thing..no blinkers..no flash..no wiper delay. Was told in this model they used a biodegradable wiring harness that causes the problem. You can have it replaced for about 1000.00 but for this year of car prob not worh it.
