new electrical problem
i just finished diff lube and turned the key /radio off. i heard something running. key is off and out. i turned the blower switch and it speeded up!.i tried turning key on/off a few times with no luck. i pulled the 40 amp fuse and killed the blower till i can look into it tomorrow.
im sure this just happened because my batt would have been dead this morning.
any ideas?

The blower motor relay may be stuck on. Access the relay by rolling the glove box down (remove the two rubber stops and let it hang down). The relay can be seen next to the green connector. With the fuse reinstalled and key to LOCK, if the blower is still running try tapping the relay with a screwdriver handle and see if it stops running. If it does the relay is hanging up.
If it continues to run, remove the fuse again and get the Radiator Fan relay from the PDC and try it in place of the blower motor relay.

replaced fuse, aok, fixed itself, for now??? pulled relay, put back. ill buy new one to be sure.
another similar problem. signal blinker runs without key 2 ways.
1 faint blink at slow rate like hazard but no lights. all the time. low drain so no dead batt.
2 today key out blink at fast turn sig rate. flip ts up/dn, lights DO flash!
wiggled ign sw a few times it quit , for now.
im expecting a dead batt soon with this intermittent on off stuff.

sorry, a 2000 cherokee sport..drove 20 miles to dinner. all ok. back. all ok ,,now.
im thinking of throwing some parts at it, a ts/haz blinker, blower relay.
i hate to mess with ign sw or turn signal, its messy.??
it runs great,smooth, but has some engine noise,rattle like ?lifters/rockers? 40-50 oil pressure running,3o idle.
thanks guys,im new at jeeps as u can tell but i really enjoy the drive.
