2005 Grand Caravan with turn signal problem

Hello,
I have a 2005 Grand Caravan with an odd intermittent turn signal problem that resurfaced. Today it started again, if I turn the blinker on, both the dash blinker lights light up but they don't blink. I had this happen before and also odd things like turning the wipers on and the headlights come on. I took it to the dealer and the multifunction switch was replaced about 1 year ago and have had no issues until today. It is under warranty, but this is aggravating having to take it back if they are just guessing. Any ideas on what would cause this?

Though I am far from a Chrysler fan, changing the multifunction switch for your problem and having it last a year sounds like a pretty good "guess" to me. These switches are notorious for failing ie, they are cheaply made. I am most familiar with Caravans and Camrys. Compared to these vans you rarely read about failed multifunction switches in Toyota products. That said, I had to change one on my 94 Camry last year. Even the best fail. The mechs at the dealer made the right move. It's not their fault they (and us) are saddled with cheaply made Chrysler parts.

If it's not another switch , they may change the combination flasher module/relay if 05s have them.

I have a 2005 Dodge caravan and my turn signal blink intermittently. Sometimes they don't work. I am going to try the multifunction switch. My auto door locks also don't work and now the AC fan is not working. Do you know how to locate the relays and fuses for these?
