Hello im interested in finding a code reader for my bmw 1989 525i. i found some between 40-100 bucks. really interested in if it could diag my problem. on a side note should a relay click? cuz i keep my battery disconnected when im not driving it. and when i connect the negative side. a few of the relays click on. also when i turn on my windshield wiper like with water and wipers. it stays on have to shut the car off for it to turn off.
Yeah thats what i thought. i found two styles muti use and some pink relays. sense i don't know what type of relays i need ill make it simple. i think although i'm not sure but i believe i need all the relays in the engine bay. starting with the two closest to the front windshield. do you have any idea on what those relays might be used for?
