ok so my car was overheating due to the fan module not working properly and that in turn burning up my fan plug that would then make the fan not work sometimes. so i had a mechanic take a look at it and he replaced the fan module and that fixed everything but now as im taking it home the i notice the odometer doesnt work i cant contact the mechanic till next week sometime but do yall think its something related or just a fluke and the gear went out or something the odometer is controlled by gear right?? could it be anything electrical cus they had to replace the fan plug?? just need some info to see if its something i can fix now thanks
