Does anyone know where the heater/AC blower relay is on a 93 Bonneville SSE?

My blower is running on high speed even with the car off. It is not one of the relays on the firewall relay center as I have pulled all of them and the blower still runs. When I pull the firewall AC fuse it will stop.

Thanks,

Hi,
I've had to replace mine a couple years ago, it is called the blower control module and it is not a relay, it is solid state, it is mounted on the blower housing. I will have to check my factory service manual to be sure but I think I had to remove the maxi-fuse center to get at it. It is right underneath the maxi-fuse center. It actually sits in the blower chamber so the blower air keeps it cool. Let me know if you need more details

Thanks. I've been in that area before to clean the crud off the AC evaporator (or condenser?). I remember having to go through that fuse panel. Any more info would be appreciated!

Thanks,

FYI did my 94 today. Got it out of a junk yard. Same problem. You have to take the underhood fuse block assembly off and it is under that. Two pluga and 4 7mm screws. Junk yard part was 10.00 bucks. NADA was $175.00 easy fix. 30 miuItes.
