1994 Jeep Grand Cherokee - Page 3 - Answered Questions & Fixed issues

could be problem wires on the crank/cam position sensors check connections and wire conditions have the fault codes read as well to check for reported faults

If you hear the noise after the engine is turned off that noise is most likely the exhaust system cooling down. As far as the light for the 4 wheel drive that requires a test be run with a special scan tool while the problem is occurring.

Fairly common problem. First try shooting WD-40 into the opening in the handle then flipping the handle several times. The mechanism tends to stick sometimes and this may free it up. If that doesn't work you will have to crawl in the back and loosten the trim panel enough to get to the latch. You cannot remove the trim panel without opening the hatch but you can get it out far enough to access the latch. Lube the latch and work it back and forth and it should free up enough to open the hatch

we cant do that, no idea at all what that means. no such thing, exists./ post symptoms first so the helper can be on same page. alarm problem? cant crank engine? engine wont start.? what?

typical jeep faults led test light and volt meter to check where 12 volts /amps and earths are needs lots of time to sort out

wow you know it's a 42RE shocking here, to see that. 42RE has TCM, the only question is how to scan it and find it. during the late 90s it was moved inside the ECU and became a PCM. no need to post 23 years of normal service parts. focus on 42RE, only it. please, my guess is , not scanning the TCM blinds you to whats UP.> read the real SM yet> on topic, chapter 21? click ZJ and read. ever seen topic , transmission in limphome mode (jeep limp-in) this mode skips gears. (due to inputs to TCM wrong or other causes) this box has an electronic governor. it also does 4>3 downs shifts and TCC lockup on overheats.260f lots of things it CAN do. below 50F the TCC is disabled, to warm it up faster. what does the OD lamp do.? the lamp tells you when OD 4th gear is disabled, now in 3rd. there are 2 speed sensor , one is a backup to main. chapter 21 all this is clearly stated. The PCM runs the trans, totally no separate TCM says you need a DRB tool to scan this TCM section... (my guess why you have no scans, and work blind,) says there is a kickdown valve, so is the cable jammed full on stuck in passing gear endlessly? do not overfill the box. read how. as some do , in a panic to get it to work , based on more is better. its not. it foams up and DOOM sets in.fast. wish we had more symptoms.? goes to 3rd gear after a short distance does that mean is starts in 3rd gear stopped? in DRIVE or LOW? and does REverse work, at all times? 1 range and 2 range ? work? at all times? (lever names) chapter 21, page 12 table. see that? elaborate all Tranny issues, hot /cold engine, and all modes of travel and direction, good and bad, (both matter @!!!!) called a shop test drive and gathering all evidence , and the 0D lamps actions. here is the step your shop skipped. step 1. what if the PCM (tcm brain) says sensor, bad, TCM, VSS, or other errors, most do, it is the not looking first, that is the problem. why replace a tranny for one bad wire, ???? that was clearly reported to you, if you only looked, (scans) I hope scans , are a REVELATION.

IF NOT SEEN ON JEEP.COMUSE STANDARD HOSES.?cant be cruse and HVAC, no symptoms stated,sad.ever heard of JEEP?not photos presented, so no assessments,possible.real jeep parts ,official....http://www.factorychryslerparts.com/productSearch.aspx?&ukey_make=1064&ukey_model=15529&modelYear=1994&ukey_category=0&ukey_driveline=0&ukey_trimlevel=0&ukey_modelRange=0&isOnSale=0&searchTerm=

You need to check for fault codes, to do this turn the key to run then off, then back to run and then off then back to run and the codes will flash out through the check engine light.

the oldest story on earth cars, from 1988 to now. the CEL GLOWS< (SES OR MIL) you have to scan it when it glows, or its all a wasted of time ever heard of intermittent. CEL = CHeck engine light, not brakes, or other warnings. my guess is you are doing the key on 3 times tests. be nice to know that. ?????? or using and INNOVA 3140 scan tool that is REAL. try to know that turning the key off, some codes are erased. the key test (i call it the key jive test) only works if you are very very lucky, its no substitute for a REAL tool. not at all. not in the least. its really just a toy. good for if stranded, somewhere yes. but not used in the shop. some errors are stored in the memory, if power to memory and the memory fuse is not blown, are stored, most are. but NOT ALL. case in point , CKP or CMP sensor errors the PCM loves to rest them. the second they clear up and does not store it. I can show a PCM running on my bench jig and show this to be true. this car has flash codes (cel flashes. and can be scanned. the latter is 10x better.

no idea at all what that means. the story is for sure longer seeing how its not stock. and how it got that way. gee. what you do is go to the store, any auto store, even walfart buy the adapter kit, now it just plugs in , but wait the connect has pig tails sure it does, it must then go to pioneer.com and bet the free manual then read the page on wire names. and match the kit its that simple. done many. actually ever-which way and ham radios too.

I believe that the alternator is bad ! Check it out on you tube !

It maybe bad gas or just water in the lines ! Try some dry gas ! And do not let your fuel get so low . Never less than 1/4 tank or you run the risk of burning up the fuel pump ! As the pump uses the fuel to cool it ! Check it out on you tube !

Check it out on you tube !

UNPLUG IT AT THE WIPER MOTOR , THEN PLUG IT BACK IN ! I T SHOULD RESET ! Check it out on you tube !

Bad coil block!

Same as any other make and model. Evaporator, Oriface tube, pump, condenser. The dual climate controls on these models are enough to make a veteran tech crazy, good luck if you have to deal with these items. There are aftermarket replacements that will fix the broken plastic door pivots, after a while the mix doors break, and it will stay hot, or more likely hang up on cold, sometimes the ac system will override the available heating capacity of the heater core, making the heater ineffective.

Can't really do that. Being a 94 it is probably a bad sensor on the drivers side key lock. They break and fall off the lock. It is a momentary on/off switch. So you can't put the two wires together.

There is no reservoir...fluid is added right into the tube for the dipstick with a funnel.

There are some cleaning additives that you can buy. Sometimes running full synthetic oil helps clean.
