I would maybe re-check work that you did to it, tps, iac, position sensor ect to rule that out(proper adjustments ect.). just a thought but when was the last time fuel filter was changed? If you could get a hold of a data logger or an OBD2 reader, any kind of scan tool, that could help to see...

Never noticed duplicate thread :???:

Could't find the thread Jimbob2001 mentioned. Not sure how to search for specific threads

There is way to check for trouble codes with the ATC To access fault codes, depress the acc and recirc buttons at the same time and hold them while you rotate the temp knob(99 and later) the left temp knob 1 click clockwise. The complete display will light up(the segment test). if any of the...

Happened to my escort after it was stolen twice. Somehow they break the locking mechanism. it is supposed to lock

My initial thought is an intermittent contact. Because of the age, thinking maybe worn out contacts? Bad connection somewhere in the line or in the connector, wiring or splice? My '91 DSM has a stupid slide contact that I put a tywrap on to keep a good contact. Do you know if you actually have...

That's what it said in the manual. And it worked for my chime issue

I think it's just part of the diagnostics that don't trip CEL. Like anything else that trip the overhead

Inside. Mine was all caked,rusty, slimey, nasty junk. Whole system was pretty bad. Hard for heat to transfer through that. It was in an escort that I got 500K out of lol Till transmission went. No Matter how many times I flushed it I couldn't get it cleaned out

Do you have the automatic zone control system-on board diagnostics? AZC. if you do there is a test(I have manual that shows how) stores historic faults and current faults, just a thought. Try disconnecting the battery and it will clear those codes in your overhead display but not DTC. Worth a...

With addition to what jpninpa asked, Wondering if the system was ever really corroded. This from experience, my heater core was pretty bad and caked with gunk, motor temp was great (even at -30C on highway) but because it was gunked up it had a hard time with the heat transfer from the core...

Because you said it was replace 2 months ago I would check the contacts. Make sure they didn't loosen off and (will need a second person to crank) if it clicks from the starter or the relay

In my Grand Cherokee wiring diagram doesn't show a relay, 3 fuses as well. Would imagine similar for your Cherokee. I would confirm power through your contacts/fuses. Give the dash some tough love to see if gauges restore. Possibly a bad/intermittent connection behind the cluster. This isn't...

Yes #1 you need obd 2 reader or have a garage check for codes( here it's like 50$) To check a lot of these things (sensors) you would need a voltmeter. I have a manual with proper values if needed. The swapping parts on a guess is a costly way to go with no guarantee. I avoided sensors because...

:shades:

Agree with the weirdness of all sensors being replaced, reasons for this? And agree with fuel system check, pump, filter, pressure. No CEL, but would check for codes any way. I have had this happen to me in a car I used to have, and a similar thing in a buddies jeep which I own now(except for...

The function of the evap emissions control system is to draw fuel vapours from the gas tank and fuel system, store them in a charcoal canister and route them to the intake manifold. So the hose(s) must be damaged, corroded, cracked ect. Do you ever smell fuel? I don't have diagrams for your...

Yes, a fuse is used for interior lights.

Just thought I would throw this out there, I find it strange that your fuse or relay never popped or cut out before being engaged and holding enough to "burned it out" Maybe something to check out
