Where should I look for these parts to purchase and what is the "sticky key fix? I am able to find a camshaft position sensor on amazon which says to fit mercedes slk320 and the Bosch crankshaft position sensor on amazon also. Where is the seat relay? For the fan speed you mention a resister board is that something that can be purchased? Sorry for all the questions, trying to get all the parts to have someone install as we can't do it ourselves. Your help is very much appreciated.
Thanks again!
