Check the fuses in the power distribution block (under the hood)
Power seats, power windows and power door locks are not fused. They would have a relay and or a circuit breaker. It should be in your owners manual.
you might have the child safety locks activated
In the power distribution box in your engine compartment of your 1997 Ford Explorer there is a 30 amp maxi-fuse in location # 10 , for your power seat(s) , power windows and power locks . Ford recommends disconnecting the battery before servicing anything in the PD BOX , which would mean that your Explorer would have to relearn its idle , the clock would need to be reset etc.
blown fuse
Power locks on Ford E-150 Econoline Vans? If the van was ordered with power locks, they would be installed. Some owners don't want them and they can be ordered without. joedi
Measure width of seats to see if you have enough space - you will have to drill new holes for mounting
Hmm, a 2002 i would say yes, well atleast it might be an option, but almost every new car from 2000 and up come standard with power locks.

They would fit, just getting them to work is the challenge.
burnt fuses
honestly the best thing you could do is get a new vehicle. Models that old that have power windows/locks are screwed once they stop working..... cheaper to just get a new car Since you say they all went out at the same time, it is unlikely that it is a failure on the locks or window motors themsevles but it sounds like there is a bad wire somewhere...you would have to take it to a mechanic to find out what wire, without extensive electrical system knowledge.
The LS is lower trim level than the LT. The LT cost more but has better features like optional leather seats, heated mirrors, heated seats, power seats also and tire size might be different. A Silverado LS is the base truck (but can have options added such as power locks and windows), a LT has more options than a LS and a LTZ has all the bells and whistles. However, you can have a LT with added options that would make it essentially a LTZ, or have a LS truck with extra options that would essentially make it a LT with standard options.
