'87 Cherokee no horn, turn signals, brake lights, wipers, blower

Probably a broken wire feeding the dash from the light switch.

Lets Look at the fuses once more the # 2 threw 5 i have seen the fuse be good but it had loss contact in the fuse box, remove the fuse and install them to see if this helps
Also at the battery there is a fuse link check here to see if this has blown or loss contact,, a new one can be spliced in if needs replacemint

Hello and welcome to FixYa . Locate the dial that controls the brightness of the dashboardlights. If the control is not immediately evident. Make sure the brightness control is turned on. If it is and the lights aren't working, the problem may be a bad fuse. Check the fuse that controls the dashboard lights Replace the fuse if necessary. If just one part of the instrument panel is not lighting up, then you have either a burned-out bulb or a wiring problem.

This should get you going. And you can always Ask Me.

check your fuses under dash use test light ground it, your doing negative test ,test light on, fuse ok.
do that each of them you must turn your keys on don't start the car , in order to check.. good luck!!

first problem generally sounds like your blower motor fried. second
problem hopefully is in the light switch itself it could be more difficult if it is behind the fuseblock. bad connections

chech fuses or ground may not be grounded good

Sometimes there are relays under the hood. There is usually a diagram posted underneath the door when you tak it off. The turn signal is usually just a fuse, which may be in your glove box(has a diagram under the door), under the driver or passenger side dash. Do you still have the manual for the vehicle?

There could be a fusible link under the hood off the starter relay that is burnt out.

I think I have found the problem. When I wiggle the ignition switch the turn signals and radio go on and off so I feel the issue is in the ignition switch. From what I understand the actual electronics for the switch are at the base of the sterring column behind the lower dash panel and is connected by a rod that may need adjusting.
