Check battery voltage with a volt meter. Voltage at ignition switch should match that of battery less 1% due to built in loss at connections and wire resistance. If not, check connections on the way to the switch, beginning at the battery to see where power drops off. Check all grounds as well.

How to replace a relay switch for a 1999 jeep grand cherokee


The relay on our 1999 Jeep Grand Cherokee was located behind the headlight on the passenger side of the vehicle. technicians at the Jeep dealership that you have to remove the bumper to get to it OR you can remove the headlight assembly and drill a hole large enough to get a socket and extension to the bolts on the relay..removed the headlight and drilled a 5/8" hole to get to the relay screws.
Why Jeep puts this relay in such a hard place to reach is beside me - - - other than perhaps they don't want it to be easily customer replaceable. Argh! Good luck.

Where do i find a fuse box diagram for a 1994 Grand Cherokee Laredo?


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.

Heater seats dont work but light comes on.


Ok it is obvious since the light is coming on you are getting power to the switch. It could be a heated seat relay. Im fairly sure jeeps use a relay after the switch that is where I would start. Check and see if the Heated seat relay, and fuse are good
