You are correct on the part number, sorry about that. And thanks, it took me a few hours of going through data sheets and vendors to find a match I could purchase. The Fujitsu is listed as a "quiet" relay, I don't mind the clicking from the NEC, it lets me know it's working before the wipers move...

As promised, this is a picture of the relay box. It shows how it is held in place with a screw and a spring clip that slides down into a grove on the right side of the glove box after the glove box is removed. The screw is at the bottom when mounted. At least this is the way one with a factory alarm looks.


And these are pictures of the before and after, Fujitsu to NEC, relay replacement.


The bottom picture show the intermittent wiper relay changed out with the NEC relay. The NEC is physically smaller than the Fujitsu, located towards the center of the cable connections.

I just did this fix on my 2000 rodeo over the weekend. I wasn't sure which relay was bad so I replaced all three. The rear wipers work now for sure, but I also replaced the relay for the front wiper delay circuit. These NEC relays are LOUD. It's really annoying. I'm either going to open it back up and try to replace the front wiper relay with one of the old ones or figure out how to insulate the box so I can't hear it... I don't know how the Fujitsu relay worked out, but these NEC ones are definitely much louder when they switch.

I'm looking at these datasheets for the relays and I don't think the part suggested in this thread is the right part. The EQ1-22111S is supposedly for lamps and LCR control, and is a "form A" relay. The EQ1-31000S is for motor control, and is a "form C" relay, which is the same form as the Fujitsu relay we are trying to replace. Additionally, the EQ1-22111S part has a 180 ohm coil resistance, where the Fujitsu is rated at 240 ohm. Ideally a replacement would be as close as possible to 240, which also gives the EQ1-31000S an advantage as it's rated at 225 ohm.

Take that into consideration when looking into this relay job, as well as the additional noise from the NEC relays. I installed the 22111S, as did some others and it seems to work alright so perhaps there isn't anything to worry about, but if I had done the research before hand I would have ordered the 31000S parts. I'm looking for a source for the 'quiet' fujitsu relays, or any other quiet relays and will post here where to buy them if I find any.

The EQ1-31000S probably would be a better choice, but the EQ1-22111S was all I could get at the time, and I know they work. If you are willing to order 125 for $387.50, you can get the originals from mouser. If I had to replace the standard high and low speed relay, I would look for some originals myself. You should be able to insulate around the relay inside the box to quite it down. Some closed cell foam or duct seal would probalby work.

I thought about insulating it myself... Wrap the pcb in plastic, stick it in the case, fill it with foam insulation... that could be messy though.

I found several other suitable replacements, however, I can't find them in stock anywhere and I've checked Mouser, Newark, and Digikey. Here's a short list of known quiet relays that will fit...

Fujitsu FTR-P1CN012N (obviously)
NAIS/Aromat CQ1-12V
GEI AR7-012-CQ6S (made in USA! well, company is in NH)

Oh, and here is a great table I found on CIT's website. http://www.citrelay.com/Relay%20Cross%20Reference.pdf
Nice spelling job on the title.

I've found plenty of others that are equivalent to the NEC's at Mouser. If anyone wants to go digging around for relays, make sure you look at the current rating, that's pretty much the only spec that vary's in all of the compatible parts. A replacement should be rated to carry at least 20A for 1 hour.

I'll likely try to just put one of the fujitsu relays back in for the front wipers. I'm not sure which fujitsu relay was bad, so I have a 66% chance of putting a good one back in.

My alarm/wiper board looks like the picture in the link above posted by Amigo2K. In that pic, I'm assuming the relay already replaced by the NEC is the rear wiper, and the one circled is for the front wipers? I need to know which one to replace with the Fujitsu. Does anyone know what the other relay is for? Alarm system probably right? I think I'll leave the NEC in that one.

My bad, GEI relays is in RI, not that anyone would probably call me on it, but let the truth be know.

Cheers.

Here's a link to a source for the Fujitsu Mouser.

The problem is you have to buy 125 @ $3.10 each. Perhaps a group buy is possible.

Anyone want to organize this?

I got a quote from DigiKey for the Aromat CQ1-12V quiet relays, 40 @ $2.925 for $117 total... I might be tempted to foot the bill and sell handfulls off to members of the board at cost and shipping. Then again, I could just end up out $117. Think there would be enough interest?

I did a lot of looking on Mouser's web site, as well as others. The only relays I could find for retail sales with the same package configuration AND the same ampere rating were the NEC's mentioned above.

I would think the relay circled in the picture was the intermittent wiper relay, since it is in the same physical location as the one I replaced on mine for intermittent wipers. Should be the same wiring harness even if the control boxes are different.

I've been having the same problem. Front intermittent wipers go out. Just today they weren't working at all and then I went through a large puddle on the onramp to the freeway and then they started working fine at highway speeds. <img src="/forums/images/graemlins/confused.gif" alt="" /> I'd be interested in getting one of those relays if that is indeed my problem and if its the same for Trooper.
