Hello All, as i read recent posts, it has brought me to ask this question. my one-key system DeLorean may be in need of door lock help - i recently 'revived' my original power locks (they had not been connected since before my ownership) and they seem to work like they should. however, sometimes the driver's side lock doesn't engage like it should when summoned from the passenger side. as i see in the back issues, this usually signifies a bad lock solenoid. my question is this: i am about to order lockzilla. i should probably order at least one new lock solenoid at the same time, correct? would it be wise to replace the passenger side one at the same time? i have no problems right now with it, but i'm sure it will eventually go out. also, some of the DMC websites talk about a 'core charge' if you buy new solenoids. can someone explain what this means to me? and should i pay the extra money to get the original harnesses included when i buy new solenoids? thanks for the tips!
