The power windows and radio dont work. i switched out the relays and still nothing. its a 94 jeep grand cherokee

i got a 94 and mine did the same thing. turns out it had a bad fuel pump relay and a bad asd relay. i switched the horn and asd relays with them and it worked like a charm. give it a try, it cost nothing. all those relays are the same

CHECK THE FUSES AND POWER WINDOW RELAY

It could still be the battery....It may not be strong enough to start it but you will still have enough to operate windows and radio....It doesnt take much power for radio....or windows Unless you move the windows constantly then it will run battery down quick.....Check battery voltage and battery connections...Also jeeps have a ASD relay which means AUTOMATIC SHUT DOWN...This could be a bad relay.........This is under hood at fuse Power Block Box.....This could of course be the starter also...Check wiring connected to starter....Sometimes it will vibrate loose and it will do nothing....And the crank sensor will cause it not to start....It is on the passenger side of engine block under and at back of engine ...You cant miss it if you can get under it.....It has another relay the same size as the ASD relay...You can test the ASD relay by switching the two and this will tell you if the ASD relay is blown...If this doesnt change anything and still wont start it is not the relay.
I am chrysler tech and have jeep manuals.......I can help you through this....I need engine size and exact problem....Does it turn over at all ?..How many miles on it ?..And does the dash lights and gauges operate when you turn the switch on like normal...?..Make sure it is in park and your foot is on the brake while turning it over.............................................Metalpoet

sounds like a fuse have you checked the fuses?

There are 2 fuse blocks. The Power Distribution Center is under the hood along the passenger side fender and has fuses and relays in it. The other is on the passenger side of the dash and has fuses and circuit breakers.

Jeep grand cherokee ltd, 1996 The radio is not working, when I switch the power on the antena motor makes a noise although the antena is always up, there is no sound from the radio what so ever, it says WAIT 2 1/2 hours but nothing happens, no tape radio cd, switch the radio off the antena makes a noise then the radio switches off.

fuse 8 40a supplies power to starter relay and ignition switch, to close the starter solenoid and engage the starter which draws directly from the battery. check to see that the starter relay is closing, if not ensure that the park neutral switch is not faulty (open circuit), it provides path to close relay (ground side) on the 85 - 86 terminals. if the starter relay does not close the starter will not run. if you have a spare relay swap out the relay for a quick fix attempt. hope this helps

no it wont work.they made too many changes with them about 2 years older and id say yes but no they wont interchange
