Windows/battery...
 

Recently i have been having off and on trouble with rolling my windows up (86 300E)...they roll up fine but take f o r e v e r, i was wondering if this could be the cause of a weak battery as the other day when i was leaving my house the battery dash light came on briefly but then went out 2-3 min later... just a thought, any suggestions? thanks

Take the battery to an auto parts and do a test under load for free.
 

or take the car and have it tested at a reputable MB mechanic.
It could be that the window tracks need lubing. Any other symptoms? Hard to start, etc, etc.?:cool:
