I'm trying to figure out why the entire hvac system is not working.
I pulled the "Fresh Air (HVAC) Blower" relay, ran a hot wire from the CE panel to pole 30 on the relay, a wire from pole 30 to pole 87, turned the ignition switch to #2, and then put the test light on pole 87. It lit up, so the relay is good. Plugged it back in, and nothing.
Then I did something I was very nervous about, but luckily had a positive outcome. I took a piece wire and bridged the 2 points on the CE panel where pole 30 and 87 on the blower relay plug in. It shot a spark, but I checked my fuses and they were good. I plugged the relay back in, and whoo-hoo, the blower now works! You know, "Even the sun shines on a dogs a** some days." It only blows through the defrost vents though, so I will be going back to your thread "Heat through door vents" to troubleshoot.
