Someone must know where the relay is

can someone please point me to where I can find the headlight (highbeam/lowbeam)relay for my 1995 cherokee jeep. I went to a jeep dealer the first one said there was no relay in the 95 jeep that it was in the light switch it's not ...the second one looked it up in the book they will sell me a high/low beam relay for $10.00 (part number 4727370aa)but they and their mechanics have no Ideal where it is located in the car. I've check chilton at the local books store and they do not list where to find it

Unless the vehicle has been modified, the headlights are powered through the switch. There is no relay.

If you are looking for the switch that kicks from hi to lo beam, I can tell you where it is on my '91, I believe your '95 uses the same interior and switches, etc. Someone jump in if I am mistaken:

It's about halfway down the steering column on the left side, held on by the same bolts that hold the ignition switch. It is operated from the multi-switch (turn, wiper, hi/lo beam, cruise) handle by a short rod running down the column.

Take off the bottom full-width panel of fthe dash (six or eight screws, including one behind the ashtray), and it is easier to see and get at. One nut should have it loose, unplug the connector, and head to the wrecker or parts store. Try asking for a high beam switch rather than relay.

John,
It is often easier to obtain useful information if you describe the symptoms of the problem you are attempting to solve, rather than presenting a diagnosis that involves the replacement of nonexistant components. (For example, the switch mentioned above is known to get out of adjustment. Simply readjusting it could solve your problem.)

What is it, exactly, that is not working correctly?

tangofox..
I've have explained the problem in previous post and seem to get the same answers that is why I asked 'just where to find the relay' 7 months ago our jeep high beam stopped working low beans did light up..I posted the problem and received help as to replace bulbs even though I explained that was the first thing I checked. now about two months ago the both h/l beams stopped working. I again posted 4 help..hoping someone could give me a clue as the next step I should take..I then received replies 'its the headlight switch' and another saying it was the 'switch on the steering column along with the directional's (one unit)..I then went and purchased a new head light switch and it didn't help, I then instead of purchasing the switch assembly for the steering column I switched it with a neighbor that has the same vehicle and again it did not help. I could not find anything that you could adjust that went from the steering column to behind the plastic covers ether I miss understand or its just this year is not the same as the older 91's. my unit comes off with two screws and unplug the harness. Now why the relay..I've been told by the jeep dealer there is a relay that is in line with the switch on the steering column that when you pull on the high beam switch it activates a relay that should power the high beams they will sell me the relay they just can't tell me where it is located..My other thoughts of why it would be some sort of relay is because both lights our now out, but when I put a probe on the connector plug of one of the headlights there is power but the negative plug is also showing power another words all three wires are hot and there is no ground going to the bulbs, In the days back I owned a couple of foreign cars where the relay for the head light in fact would just produce a ground when you hit the switch..I might be way off mark but I do know if a relay is stuck or moister gets in it you do get erratic functions. also the back lights / taillights etc..all are working correctly the high beam indicator in the dash works as normal.. I'm very thankful for a forum like this and I hope I'm not sounding condescending I realize it is almost impossible with electrical problems to diagnose ..over the internet. but I've been told so many different stories 1) the relay is in the light switch in the dashboard. 2) it is located behind the steering column 3) it is on the left side of the radiator in the front of the car 4) there is no relay , 5) there is a relay 6) its on the steering column. Also the wiring schematic that comes from mitchel auto repairs shows it next to the radiator which I can not find. but again it says there is a relay..also we had the car since 1996 and it has never been a problem and no one has ever done any wiring changes. thank you very much for all the info that all the people have offered, I will keep trying and hope someone with the same 1995 cherokee had the same problem and found the solution.

Im sorry about your beans.

I cant remember who I was sleeping with 7 months ago, so how can anyone remember a post about headlights from that long ago?

That's a multi purpose relay but looks like it has nothing to do with headlights. This reinforces MY belief that there is NO headlight relay. Looky here (from a Mopar parts dealer look-up):

my old mj used to do many of the same things, one day the lights would work the next they wouldnt. no high beams, than all if asudden tehy just stopped working etc. i replaced the switch, the relay, the bulbs, and eerything else that seemed to be part of the system. one day an guy that works at a jeep dealer told me to check all the different wiring harness plugs under the hood, specificly by the firewall he thought one of the had something to do with the lights. sure enough there was a plug i want to say it had 6 wires going into it that made teh lights comeone when i wiggled it. turns ut when i cleaned it p the housing of the plug was cracked and the wies got loose not to mention dirt, mud, rain, oil, and grease. i cleaned it all up and taped it up good and water tight and with copious amounts of dielectric grease i neer had a problem with it again. i dont know if its the same on yours or not but it could be worth looking for.

John, someone else has a similar problem that you do. His problem turned out to be a faulty ground. Here's the link. Stu

OK... 0638094 comes up "part number not found" and the second (or should I say third) part number shows it being a "Headlamp Delay Module". See below:



Item Number MSRP Core Price Price
56009324 $52.25 $0.00 $34.49

MODULE HEADLAMP DELA

Part number 56000636 was superseded by part number 56009324.


Good Luck!!

reading systm wire diagrams

I'm back trying to locate the headlight problem. I took a ground wire and attached it to the ground wire at the headlight plug...wow when I turn on my light switch the lights work. so now I'm following the black ground wire from the headlight lamp towards the on / off switch thinking somewhere along the line there is a relay or bad connection. my wiring diagram shows it going to the 'headlight delay module) says it is 'left side of i/p' does anyone have any idea what 'i/p' stands for?..or where I find the delay module
thanks for all the help jlm

John, The headlights should connect to chassis ground G106 through a plug C106. G106 is located somewhere on the drivers side chassis or fenderwell. I don't think it's important to find the break in the ground wire. Just run a new one. Stu
