What I recommend is that instead of a manual resettable circuit breaker (which is expensive and not available everywhere) you put a fast-acting fuse in. 10 amps should do it but on some cars you have to go up to 15, especially if you like to click the locks a lot or have a remote. Definately replace the relays but you MUST fuse the input if you are going to use the origional lock module. If the lock module doesn't work or seems like it works sometimes, then you must also rewind the locking solenoids in the doors because they are probably burnt. In that case you will blow the 15 amp fuse quickly. That is a sure way to confirm the solenoids are "cooked".
