Well, Hi this is my first post here to this wonderful forum site!
I have a good condition 1994 DX with ~145,000 miles and it is still a really strong and well-running vehicle. I have owned this car since it had about 30K on it and I must say that this has been one incredibly reliable car.

Problem:
I was diagnosing an overheating problem (main engine fan not running at all) and I removed the large relay in the main engine fuse box (I believe this is Cooling Fan Relay #1 - or so I was told)
and I misplaced or lost (!!!) this relay somewhere in my workshop while working on other projects. I travelled down to the local Mazda parts dealer and ordered a new thermoswitch (primary fan tested good with wires run straight to battery) and was going to order a new cooling relay, but believe it or not they could not tell me what part no this relay was.

Can anyone give me this part number for this main cooling relay found in the main fuse box in the engine compartment for this 94 DX model? I hope that by replacing the thermoswitch (any insight on this replacement or testing would be helpful) and this main relay (since I lost it) will help get this fan back to working and this car stop trying to overheat. --- Is there anything else I need to check or investigate besides these 2 items for the main cooling fan problem?

Well, thanks so much and I look forward to posting and learning much more from this site. Thanks again!

Sorry to be a pest... but do you have the part number for the thermoswitch? I've found that they're often broken in half, but the dealer gave me the wrong part number.

Tell you what. I will trade you. You first on the cooling relay.

Hehe, OK, I'm going to try to get the entire part sheet, actually, but that might take a while.

I am just asking is that you walk out to your car, pop the hood, open the main fuse box under the hood (drivers side black box near battery) and open it up and write down the Mazda part number (or all numbers on the part) that is in the "COOLING FAN RELAY" position within this box. I lost this part and Mazda (well my dealership) CANNOT figure out what the Mazda part number is supposed to be. Seems odd to me, but then I have heard worse things.

I guess I may have not been clear on this and I so apologize to you for this my friend. Let me know what you find on this and thanks so much!

OHHH, now I understand.




This what you were looking for?


LA10 seems to be the only indication of part number. I suspect the other part means 12Volts, 10amps . The bottom one is probably a serial number as this is different between my two cars.

Mazda part numbers go XXXX-XX-XXX or so, so it isn't really giving you one of those, but at least you have something to compare to if they bring a part up to the counter.

Good luck
