2004 grand Jeep Cherokee is there a switch to put it in 2 wheel drive and where is this located


Not all cherokees were fitted with a 2 wheel drive option. You should have two shift sticks in the centre console. Your normal Park, Reverse and Drive selector and a smaller, shorter stick to the left of it.
This shorter stick will show you your drive options.
If you only have the first three listed yours is permanently 4 wheel drive, sometimes called AWD, (All Wheel Drive).
Starting furthest away from the engine, they should read as...
4Lo - Low ratio 4 wheel drive used just for 'off road' driving.
N - Neutral. This disconnects ALL drive to ALL the wheels.
4 FULL TIME - High Ratio 4 wheel drive. Normal road 4
wheel drive.
"Options that might not be fitted".
4 PART TIME - Automatically switches from 2 wheel drive
to 4 wheel drive if the rear wheels start to lose grip.
2WD - Dedicated 2 wheel drive only. Power is sent to the
rear wheels.

My jeep jeep cherokee sport vehicle will not start some time until i wiggle the gear in park or netural


This could be so many things. Bad battery connection, starter starting to go, fuel pump starting to go, relay/fuse broken. I would start with your battery and connections.

1993 dodge Grand Cherokee with a 318 hard starting when cold until things under hood click and fuel pump runs.


Your jeep ecu is in need of repair. It has what is referred to as the delayed check engine light problem. If you'll notice, next time you try starting the jeep, it will not start when the check engine light finally comes on, on the dash. The fuel pump will only come on when the ecu finally energizes the relays, and that's when all the clicking starts. Look on ebay for an ecu repair service.

I have a 1999 grand jeep it cut off when im


I just had this problem on my 1996 Jeep Grand Cherokee. Once the engine got warm, after about 15 to 20 minutes, the car would just die at random times, sometimes when doing 40 mph and sometimes at idle.

I ended up changing the Crankshaft Position Sensor and it cleared the issue.
