I just recently purchased 1998 ml320 had to immediately have the AAM replaced due to a key recognition issue. When picked up from the dealer, the radio was not working, no power whatsoever....not even asking for code....fuse looks good.

Also, the headlight switch turned to full on will turn on the park lights but not the headlights. If I press the fog lamp switch on the dash they will come on......is this supposed to be like this.

Also will not engage to Low Range........light will flash several times when started and then go out......if i push the switch, it will also flash several times but will not stay engaged. WTF

I suspect that these problems may all be related to the AAM........which was supposedly replaced. Here's the kicker.........the day after I picked up my car the dealer went into recievership.......

Any comments or advice...

Thanks
