front diff wont engage.

On the weekend I wax out wheeling and dropped my rear drive shaft. Everything was work7ng great till the, I couldnt even crawl out in front wheel drive, my front driveshaft would spin but the wheels wouldnt. I figured out the problem with my rear (it wasnt a 8.8) and its getting fixed right now, but would could be the issues with my front. I drive a 90 yj 2.5.

the check engine light and coolant sensor bad warning on my ZJ arnt on. I think my jeep might be broken :(

The CAD (Central axle disconnect) probably isnt engaging. Could be a bad actuator, tcase switch or a crack in the vacuum harness to it. You can fix the issue or permanently lock it in
