1997 Jeep A/C failure

its not a FORD, why would you thing a jeep is a ford?
is stock car , USA stock car (we are USA forum, )
then this book cover all that. its called the FSm.

ever wire, every bit,

why assume it has an inertial switch. ?
here is the truth.

1. check all fuses first, (using a meter, no guessing)
2. check fuel pressure, ah 0psi cranking,
3. Check engine light must glow key or PCM is dead. (fuses)
4. I check voltage at fuel pump relay output, its 0v cranking
5. bad relay or PCM sees no spark.
6. got 12v there, but not at pump cranking, bad wire .connector on way to pump.
7. if 12vdc at actual pump and dead pump that is a bad pump. (0psi pressure)
   

can i guess you replaced both for a buck? yes>?
tails are park , there are like 20 lamps on park
all are dead?
click TJ
and 93-98
then wiring
and read the schematic. see where to check voltages.
its that easy.

no computers no BCMs,. just 2 bulbs, a switch and fuse.

if the fronts work it is bad bulbs
or TRAILER WIRING HACKS FROM H3LL.

sure, do you have 12vdc to the lamp, in park?
if not work to the source , the relay that the operates that.
alldata.com has the schematic.

fact 1, license plate feed runs off left park.
fact 2, the park relay feed both left and right park fuses and lamps.
so, fuse 7 is left, and fuse 9 is right.
did you only just look at the fuse, and proclaim, good.
or use a voltmeter? or use ohms to test fuse 7, oops
fuses that look good, can be bad. 0 ohms good, infinity is bad.

use volts, is there 12vdc on both sides if fuse 7,>?
yes, then fuse is good, parks turned on.
no, the output side of fuse 7 is 0v. so fuse is blown
if input is dead, the relay is bad, but how can it , if right works, answer.
it cant be bad.
so what is the voltage all the way from the fuse to the lamps.
id bet, (fuse good an voltage good at fuse 2 sides) that the line is open. cut wire, corroded connector.

the BCM turns the relay on, this part works.
so.... its just a break in this simple copper path.

use a voltmeter, it will not lie to you, trust it./

The ZJ , jeep
the FSM covers this.
look here. its there.

loose wiring can cause failure i would try a engine harness out of junk yard

Interesting.
White smoke is usually burning coolant.
You should be loosing a fluid, something has to be burning to make the smoke.
It could be a very slight drip onto the hot exhaust manifold or pipe if it is only happening from under the hood.

Your clutch is not being energized - ergo the compressor will not run - no AC. Get yourself a schematic so you can intelligently trace all of the wiring to your clutch and locate the source of the problem. Afterthought - check out the thermostat setting? That is in series with clutch winding and .............................

Review ths Repair Manual ZJ-Secc-8W-Wiring-Diagrams (page 7, 9 and 10 for location, details and description). The diagramas can find it in the next pages.

I hope help yuo with this (remember rated this help). Good luck.

these particular vehicles are almost always related to a bad cam\crank sensor,

Do you have the owner manual???? Are you might can go to a junk yard and fine a cover out of a wreck jeep???? You should be able to also go on line and fine a wiring diagram????
