And the AC blower stops working…

We pulled out of camp this morning (a small road side park) and got to Marquette relatively early for sightseeing before continuing to Munising for a boat tour of the Pictured Rocks seashore.

We stopped into Meijer’s for some fresh vegetables but when we got back to the van and started it, no AC. Awesome; it’s 85 degrees out and I’m really not sure how to begin fixing it.

I did a walk around and inspected the engine. Then I looked online for fuse diagrams (Mercedes doesn’t include them) and had to go through two fuse boxes looking for popped fuses. One major bank of fuses is under the drivers seat, so the whole seat needed to come out. No bad fuses to be found.

Next, a look at the back of the control unit since there were some folks in the forums who have had solder joints pop on the circuit board. That required taking the radio apart to get to the panel off to access the AC board.

Nothing worked so we resolved to get to Ottawa as quickly as possible to get the van serviced.

Driving down the road, we felt cool air coming out of the vents, a sign that the AC is working but that the blower fan was busted. So that’s the next step to test.

But that’s for later, we’re on the way to Munising for a boat tour so we enjoy what’s left of the day.Read more
