Previously on "The Mystery Machine"... I replaced/repaired the EATC controller and got my AC back and all was good in the world... for a few weeks.
Then, I went to pick up my daughter from school one day and the main AC blower was not coming on. I know the rest of the system is ok because I put a test light on the compressor clutch so I could tell when it was engaged from inside. Said light was on when expected and the rear blower was blowing cold. Searched the forum, tried to find the blower relay with no luck, checked the 2-wire connector on the blower motor and the blower started working again.
Today it wasn't working again, so I again tried to find the blower relay, but what I see doesn't match what's in my manual. Before messing with the connector again I tapped the blower casing with my magical screwdriver and presto on came the fan!
So...
- Where the heck is the blower motor relay?! All I could find was this (see red in pics) one similar bus in the far front/passenger corner under the hood in front of the air filter, but it doesn't exactly match what's in my manual and there's only one relay in it that is apparently NOT the blower relay. I'm wondering if someone has bypassed the blower relay at some point in the past. Is that something people do? I see a couple of wire crimp connectors near the blower that might be from a bypass.
- What is this empty round connector in these pics? That's as mysterious as the one mandatory light switch in each house that no one knows what it does!
- Do these symptoms on the blower sound familiar? I was going to check the blower connector with my multimeter but then the blower came on. I'll try to get it next time!
- Any other thoughts or suggestions?
Thanks!
