High beam switch on 94 Grand Cherokee won't stay on

SOURCE: 97 Jeep Grand Cherokee lights won't work high

Use a test light, or a ohmmeter and check the wires at the wire plug under the dash that go to the multi-function switch thru the steering column cover, you should have continuity between #18 and #19 low beam terminals, if not the switch is bad and will need replaced. it shows how to check this in Haynes 1993 to 2004 Jeep Grand Cherokee repair manual #50025 page 12-6. To replace the switch in the column cover, remove the negative battery cable, wait 2 minutes to disarm the air bag system, leave cable disconnected, before removing the column cover.
