88 cherokee, igntion actuator problems??? key turns to all positions with difficulty, but when turned to engage starter, will not start and disables radio, cig. lighter, turn signals, wiper blades, and blower fan motor. Is this a short in the actuator and if so how can i get rid of it completely and just go to a standard dash installed ignition

When you turn the key to the start position what's happens ? Nothing , do the lights dim ,dome light ? The starter doesn't engage an spin the engine ? Is the security light lit on the instrument cluster ? Anti-theft system problem may disable starter engagement . You say battery is good ? How do you know ? Headlamps shine bright ? Do you know how the starter circuit works ? Does it use a key start ?
Circuit Description (Key Start)
When the ignition switch is placed in the Start position, a discrete signal is supplied to the body control module (BCM) notifying it that the ignition is in the Start position. The BCM then sends a message to the engine control module (ECM) notifying it that CRANK has been requested. The ECM verifies that the transmission is in Park or Neutral. If it is, the ECM then supplies 12 volts to the control circuit of the crank relay. When this occurs, battery positive voltage is supplied through the switch side of the crank relay to the S terminal of the starter solenoid.

Won't start how ? When you turn the key to the start position what happens ? Anything ? Does the starter engage an spin the engine ? This would be a crank no start condition which would have me check for spark at a plug wire or hook up a fuel gauge an check for fuel pressure , doing a compression test . Or nothing happens when you turn the key . Which would have me test the battery ,voltage drop test the starter circuit , looking at a wiring diagram to see what all is involved in the starting circuit , relay , park neutral safety switch , PCM/ECM - engine computer .
You need to add more details .

Should it still start after bypassing the lock and using the igntion control module with a screwdriver?
Your best bet take it to a qualified repair shop !

First thing to do is look at the dash lights when you put the switch in START position. If they blink or dim, you may have a faulty battery or poor connectivity.
Next try jumping the starter. You'll find a starter jumper at almost any auto parts. If you get no result then the problem is with the starter, If the starter turns then the problem is in the starting circuit from the switch to the starter relay.

Test your battery and starter by doing a voltage drop test. Put one test lead of your meter on the neg side of your battery, one on the positive. Check voltage. Make sure that you are actually connecting to the battery itself and not the terminal ends. Should read 12.8-13.2. Keeping the neg in the same location move the pos to the terminal end, engage starter, meter should read above 10 volts. Continue testing down the pos wire to the starter, checking voltage, until you find less than 10 volts. If the voltage is good at starter, have someone turn key to the start position, tap starter with a hammer. if starter engages , replace starter.

I would lean more towards your ignition switch being bad. Although you could be right I have not seen that problem very often. More often than not its the ignition switch. Good luck.

first check the battery make sure its fully charged then check fuses and relays then check startor motor and if it is not any of these it could be the igntion switch good luck

Check your starter relay if you are positive both battery and starter are good. Best of luck

I would change the starter out and that will fix your problem

The problem is either in the mechanism that pushes the rod that activates the ignition switch from the key lock cylinder, or the ignition switch is defective.
