Update: I got the second replacement relay from FCP today, and...it works! Hooray! So they sent me a bad relay the first time, after all. Wish I hadn't paid for the rush shipping the first time. Anyway, for anybody who might be interested, here's a link to my companion thread at volvoforums: http://...

I send an email to FCP last night, detailing the problems and the tests I've done to check the relay. They called me back today, and they think the relay they sent might be bad, so they're sending a replacement. For now the fan is hooked up to the battery, with a switch and a fuse, so that I can mak...

The needle position on the temp guage b/w warm (85deg C and 105deg C) is only a smidgen above middle. Volvo did a really bad calibration on these guages. Use your OBD device to give you ECT reading. At 105 deg C your fan should come on. To get it to 105 deg you will need to rev at 2,000rpm for arou...

I'm getting 12v though the red wire, so I don't think it's a power problem. Did FCP send me a broken relay?

I'm seriously stumped here. Would appreciate any help. BTW, after disconnecting the battery for a while, the CEL went off, so that minor problem is solved. Anybody have any experience with a universal temperature switch for the fan? I'm thinking about maybe just bypassing all this complicated and ex...

I've been looking at a wiring diagram of the cooling fan system, which is entirely new to me. I think I figured it out pretty well over the last half hour, but please bear with me if I'm way off. Since the fan works, I figure I can ignore the red and green wires that are clearly attached to fan (the...

I hooked the fan straight up to the battery again, and it still works. When I jumper the new relay to the car, it clicks just like the old one, but the fan doesn't turn. Is it possible that FCP would send me a junk relay? Or maybe I'm doing the relay jumpering wrong in the first place. I started the...

Boy, I wish I had. Neither O'Reilly or Autozone had the part, so I ordered it. It finally got here tonight. And it's not even Volvo brand. It's "German-quality" KAE brand. But now I'm not sure if that was the problem after all. I got it installed, but the fan still doesn't come on. Not whe...

So I'm still waiting on the relay (apparently 3-day shipping for UPS means 3 business days, even though they ship 7 days a week--misleading). Today, I had to move the car from one side of the street to the other for street sweeping. It started up fine, the coolant level in the tank was the same befo...

Yeah, I was worried about it burning up. Better to just leave it alone, as much fun as it would be to rig up the wiring and switch.
