okay so recently we got a lot of snow so I was using my 4H setting like usual. I saw a check engine light, so I took a look. all the main vaccuum hoses were disconnect, so i reconnected them and now my "part time" light turned off and my Jeep will not engage my 4x4. I hooked them up correctly and i have put it in neutral, tried to reverse, and tried when i was driving to no avail, any help?

well i lost control in the snow lol and slide all the way around where i then hit a curb broadside. that was today after school, maybe that was it? but the light for part time was on until i turned off my XJ, hooked them back up, and started it up. I'm not sure if its connected, where exactly is it located? lol thanks for the reply!
EDIT: it was more like 2 inches of ice and seven of snow. I was going 25 or so and hit a bad spot i guess, locked up the brakes like the rookie driver i am haha

I didn't look today, it was 3 degrees and i didn't feel like crawlin in the ice and snow. I'll check tomorrow. It might be it because I hit that curb going kinda fast and it didn't feel the same afterwards
