power door locks on 97 dodge ram

I recently installed an alarm and keyless entry.  I believe that this truck uses the 5 wire reversal set up.  well it worked great for about a month or two. now drivers side pdl switch will not work at all and pass will only lock.  tha alarm will lock the doors when it is armed but will not unlock them when disarmed.  any help would be great.thanks

Sounds like something got messed up with you unlock relay.  Double check make sure the wires are connected tightly to the relay.  If they are try testing the relay, you never know the relay could be bad.  Hope this helps
