Hot day only - Turn indicators come on

Hi.
Have 2008 Prado. D4D
Turn indicators come on (both), only on hot days. They go off after a time but come back on.
Flasher can be heard when off or on when switched on, indicators and flasher work ok when this problem not evident. Disappears when I stop turn everything off and start up again. Sometimes have problem getting alarm to set with keypad activation as well, is that related.
Appreciate your experience advice here please

Also need reputable Service Shop - lady is due for service.
Fuel economy has drifted somewhat as well.

Thanks in advance GJT

This is symptomatic of an aftermarket alarm that has ingested water or just developed a fault. Remove any connections to the indicators and see if fault persists!

Fuel economy has drifted somewhat as well.

Have a read through the 120 engine threads. Plenty in there about getting the injector feedback values checked and injector seals replaced. Filter replacements need doing routinely too. Be careful before it costs you big dollars.

Really weird now.
As many may know we have had some HOT days of late,,,,, yep not a problem, beats me.
I haven't done anything except head and hands poking around with flasher one trying to feel where the bugger is.
Other than that nothing.
Thanks anyway - gjt
