Just replaced ignition switch in my 94 Escort Gt.Now the wipers,heater blower and sunroof don't work.Please tell me what to do next.

If the problem began when you changed the ignition, then the problem likely is with the ignition wiring. Check again to make sure it was all reconnected properly. Double check your fuses too.

As mightymoose said - go back and check the wiring at the ignition switch. I don't have a diagram for the '94, but this diagram for the '95 shows the fuses for those items - heater blower motor, power windows, sunroof and wipers - as being fed from a single wire coming off the ignition switch. It's black/red, leaving the switch on connector C236, then runs via splice point S266 to connector C231 at the interior fuse panel.

You'll probably find that the fuses are intact, but if you check them for voltage with a 12V test lamp or multimeter then you'll likely find there's no voltage on any of them, so investigate that black/red wire. This is the wiring diagram:
