BMW E30 325 Auto To Manual

Hi mate, One more question, My car radio turn on and off and the wiper arms seems too slow. The car (BMW E30 325) has recently gone from auto transmission to manual. Do you think its the battery or the alternator dying?”

It could be either going out. First have the battery load tested and replace it if it’s low.Then have the alternator checked in the car, any good mechanic and many auto parts stores will do this for free. If both check out OK, then you’ve got wiring problems somewhere. Often the wiper motor grounds will go bad making the wipers go slower. And I pity the guy who swapped out the standard transmission in that BMW, that’s a royal pain of a job to do correctly. So much has to be done, that may have messed up the wiring as you do have a lot of work to do under the dash to put a clutch assembly in.
