Autozone have some popular workshop manuals for free on line once you register (for free) on their website There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate

First thing to check are the fuses.
Thank you for your reply. I did check fuses and the closest one I could find said rrpdl. I thought it meant something something power door locks. It was a 10 amp. It was ok. I thought it might have been a higher amperage fuse than 10 amps However I don't see anything else described as Power door locks fuse.
