Question about 1994 Jeep Grand Cherokee

1 Answer

1994 Jeep Grand Cherokee limited 5.2l 4x4

My Jeep is having a serious wiring issue. I have no cover on my PDC to tell me what fuses go to what and what all the relays go to, and the the problem is this, if I pull a 15 amp fuse I have instrumet cluster but no interior lights, no info center, and no radio but if I put the fuse back in it gives me interior lights, info center, and radio but instrument cluster. chiltons repair manual does not tell about the PDC wife has read all pertaining info on PDC and there is no diagram of the relays and fuses and what they all go to because I believe this is where the problem lies. can you help?

Location blower motor relay 95 jeep grand cherokee laredo


easter egg hunts 101. what are the symptoms.?
did you check all fuses first/ that be , first
does it blow on high?
the book covering this (FSM) is free to read.
we dont need to cut and paste it , every time asked.
here it is.
it's in the PDC
read chapter 24 yet, HVAC
then 8w (wiring) 8w42
it's all there. and not fake books, it's real the real deal from jeep.
first off the GC has 2 type HVAC sold day 1
manual system
and automatic, ATC
they are totally different. so no one can answer you, lacking that fact.
lets now look at both (extra work)
the manual system has no relay, in the PDC, there is on inside the heater control but is not user serviceable.
does the blow work on HIGH>?????????
the ATC has a large relay. but is not in the PDC, its on the side of the HVAC per below drawings

chapter 24 cover this, why not read it first?

http://www.morris4x4center.com/knowledge-base/index.htm?utm_source=cj#service


page 8w -42-9 (ATC version only) 1 part of a complex system.
26147818-kvl5e4kdfcykuopgofwmpgkg-5-0.jpg
with the free book
a $10 volt meter all this is easy to diagnose.

the manual system the blower is hot. (fused F11 pdc)
the manual system the dash control, grounds the fan
on HIGH. if not on high does so through a RESISTOR block
that R is a relay but is part of the control. (buried)
so if you ground that wire below, called c7
the fan must blow, or fuse F11 is blown.
easy no? if the relay R , right coil is not 12v then that needs to be corrected, if fan blows hotwired, and R is not 0v out.

blower dead on high?

Vehicle information Center and radio fuses keep blowing at the same time. 96 jeep grand Cherokee limited. Help !


the fuse has only so many loads no actual fuse stated.by you.
there are more than one fuse related to a radio, besides the one marked RAD. so... why not tell the exact fuse.......????

we disconnect each to find the one that is shorted.
the fuse prevents the wire fire, so... do not up the amps.
ZJ , jeep it is. 96

fuses 3
FB 12 (fused dimmer to radio and other places
FB 15 main radio power,(run -acc)
PDC 17 dome lights and radio memory wire....

you need to know what fuse, then look in the FSM
and see all things wired to that fuse.
the starting page is
8w-47-2 (radio) (posted 100s of times)

http://www.morris4x4center.com/knowledge-base/index.htm?utm_source=cj#service

does fuse hold if radio is disconnected?????
lets pretend fuse 12 blows
see page 8w-11-8 fuse 12, feed.
the next page covers fuse 15....
see?
you need to look at all feed wires to the fuse that blows
that includes options, and aftermarket hacks to car.

Im installing speakers, amps, ect. and since i purchased it used i don't have an owners manual for my 1994 jeep grand cherokee. i dont know which fuse is for the radio?


It should say on the fuse diagram on the cover. You might consider running a new wire directly from the battery, fused of course. Then run a big gauge wire directly to the chassis for the ground.


Please mark this helpful if it was.
