Heater problem
1994 Pontiac Bonneville 6 cyl Front Wheel Drive Automatic 174K miles

The interior heater fan stopped working. It was working fine. It has no blow at all. I looked in the fuse panel, but don't see a fuse that goes to the fan. I figure there has to be a relay or something that is tied to the heater A/C control. Where is it?

Hi, thanks for the donation. Hope the diagram is readable? Not only check the fuse, use a testlite on the fuse circuit, make sure it is hot. The fuse under the hood is hot all the time, the one in the interior fuse box, goes hot with the key on. The relay is under hood center, firewall. You can see the wiring colors on the connector.
