Technical Support / Re: Discharge capacitors / Replace AC reversing coil
« Last post by Bill Lampkin on July 03, 2020, 04:20:00 PM »
After a little more thought, It can't hurt to short out the caps before working on the roof AC, but, as far as the reversing coil goes, I don't think that is part of the fan motor or compressor circuit, so there should be no shock hazard on the reversing coil wires, from the caps. Just check for no AC voltage on the reversing coil wires before you dig into them.

Adam,
The ACME blower diagram is available in Coach Assist. As Fred noted, the blowers for the dual blower system have opposite rotations. (I know as I spent a day+ "troubleshooting" a blower that was rotating the wrong way  :) ). Since they are not grounded by the case but have pwr & gnd connections, reversing them will reverse the fan rotation.

    Adam,
As Gerald has stated the 2 blowers are just above the throttle and easy to get to. They are available at most auto parts stores like Napa. Just a heads up: one has clockwise rotation and the other is counterclockwise rotation. Fun project for a Saturday morning! Blessings & Joy, Fred

Adam,
On my 2000 Marquis both blower motors were easily accessible under the dash by the driver's feet, and if you have a late 1998 Marquis with dual zone dash A/C, yours should be very similar. However, if you have an early 98 Marquis that is on an Gillig chassis, the fan motor location my be quite different. Also, if you have the standard Marquis dual zone dash A/C system, it has two blower motors, so you need to determine if it is the driver's or passengers motor that needs replacing. Almost any auto parts house will have a motor that will fit.

One of our dash fans lost its bearings a few years ago.  Mike Flowerday installed a new fan while I had the coach at his Summer residence in La Pine, OR while getting an Aquahot service and replacing the center roof AC.  The dash fan job did not take him too long to complete, less than an hour as I recall.  He went through the dash cabinet forward and between the seats into the middle of the dash near the floor.  That cabinet is where we keep the auto dish controller and receiver for our DISH TV system.  He pulled out the dish controller and DISH receiver, and was able to reach through the cabinet to access the fan.

Yes, my residence is Hermiston, OR.  I have owned the house there since about 1991.  In January 2019, Leslie purchased a house in the Foothills of Yuma, so we travel back and forth, trying to be about 6 months in each location - travel South in October and travel North in April.  She adopted to become a resident of Arizona this past year.  I will likely do the same... given the way Oregon's politics are moving.  Fortunately, Eastern Oregon has not changed much yet, politically, that is.

Our '98 was the Acme AC system as I recall.    Diagram may still be available through google.

My dash blower is making a loud screeching noise when on anything above low.  Has anyone had to access the blower and motor, and how is it accessed?  Haven’t really torn in to it but it seems to be behind the little wood console.

David, Don't you live in Hermiston? I seem to remember that's where you hang out in the summer. We left there in 2012 now in Wickenburg, not traveling this year.
