My 2003 montanas door locks on the switch quit working and the switch overhead for the rear power windows quit working . Any ideas???

had checked all fuses but that was not the problem.not sure what relays to check, but is there also a relay switch under the dash next to sterring column for door locks? can here it clicking when you use the remote to unlock.the remote will unlock doors and lock them had checked all fuses but that was not the problem.not sure what relays to check, but is there also a relay switch under the dash next to sterring column for door locks? can here it clicking when you use the remote to unlock.the remote will unlock doors and lock them

most of the relays are marked what they are, the only ones that i know of are under the hood where i recommended to check, and 1 under the instrument panel, or near fuse box area. most of the relays are marked what they are, the only ones that i know of are under the hood where i recommended to check, and 1 under the instrument panel, or near fuse box area.
