Hey guys. I'm a long time lurker, finally doing some real troubleshooting instead of throwing parts at it (aka "rebuilding").
The blower has always only worked on 4 but recently started cutting out randomly 2 months ago. It would typically come back on after hitting a large bump on the highway. More recently it cut out again and when on 4, now sounded like it was on 1 accompanied by a low-pitched howling noise and a variable, very low speed.
I'm following the FSM starting at the blower motor relay. The relay passed all tests except it reads 68.8 ohms when the FSM calls for 75 +-5. This isn't too far off factory specs so I don't think this is the root of the problem.
The next step is to test the harness connector for the blower motor relay. The problem is I can't get the harness out without breaking it, to get good access to the terminals. I pulled the white plastic piece out of the middle of harness but can't get the harness to budge.
What am I missing here?
