Ok, so I just got a 91 montero ls, don't really know much about cars to be honest. I'm having some issues with the front locks, it doesn't look like there is power locks on it, there is power windows though, the key will not lock the car doors, and neither will pushing them down, it doesn't let me push down the locks, so I have no clue what to do, the back locks work perfectly fine, its just the front locks that won't go down. Help! Please.
