When you bought a van with such high mileage and without any maintenance records you have to spend quite a bit.

 

Right on the expenses! Thank you for the parts lookups. I am writing them down. I cant find the side with dual door - window pop out bracket either. I had to tie it shut carefully. Eek

 

Let's keep the topic on this thread abs (yellow) and brake (red) related. (revise and move to econoline if at all possible)
From your other thread you said with parking brake fully stepped down and engaged, no red brake light on dash.
Does that mean it didn't prove out because you never seen that red brake light since you bought the van?
1) If that is the case you need to remove the instrument cluster and check on the bulb
Check pdf below. Once you have this under your belt, upgrading most (not all) of the bulbs to led bulbs could be your future project.
Additionally, headlamp switch is tricky, check here
Transmission range indicator is most difficult the first time, check youtube.
2) or you have a bad parking brake switch, check this thread.
only 1 screw holding it, remove it for a bench test, it's a normally-closed switch so use your multimeter and check on continuity, at rest it beeps, when you press on the button, no continuity no beep.

When your red brake light is not working, you wouldn't want to drive with the parking brake on by accident.
