Not sure when they stopped working as I don't often use that function.

All windows function normally using door switches

All 4 windows are affected.

All doors lock/unlock normally using keys.

Keys had new batteries recently and not sure if windows worked after changing batteries.

Car battery was disconnected Sunday while replacing Heater blower resistor.

Any suggestions gratefully accepted.

Forgot to say - front passenger airbag was also disconnected/ reconnected on Sunday.

In the absence of any advice,  I did nothing. Today they started working again. 

I may try the same technique for other faults!  BB

Sorry just seen this, after the battery has been disconnected the car would have had to re-learn the window operations. You might need to do the one touch down function on the windows again too.

 

Push and hold the switch down to get the window right down and continue to hold the switch for a few seconds after that then repeat with the up position if you're not sure how to do it.

Thanks Rich, handy to know for next time.
