well since i always use these forums when i have troubles with my mercedes i figured its time to make an account.
i have 2 problems. first one is this morning the front window defroster randomly turned on full blast while i was driving and wont turn off unless i turn the car off and remove the key from the ignition everything else functions ac wise but the defroster wont turn off.

the second problem im having is the turn signals will work sometimes consistantly but at otherr times will flash slow then shut off or just get slower and slower then after i turn on windsheild wipers the turn signals work again for short while. please help!

this forum has been a life saver to problems on this dam* car

 

1.) Sounds like you have a short in your AC/heater system...

2.) You have a bulb or loose wire to one of your 4 blinkers
