Yeah, I suppose it's a bit different on a van...... Just not familiar enough with those. Not even sure if you can get to the blend door without some disassembly.....

 

Does anybody know where the fresh air and recirculated air comes in on these vans? Any make-shift filters that ya'll have seen installed before?

You can't tell from the picture, but that fuzzy/dirty structure to the right is the blend door(I think). At any rate, it pivots from the back and swings left to close off the area in the middle of the photo with the seal that needs adjustment. I think that is the blend door.

Do you know if it activates with the vehicle turned to on, but not running? I guess I'll give it a try.

Thanks,
Matt

 

Check Amazon for the blower, probably closer to $50 for one. One thing about blowers these days is to test for rotation before installing. All too often, I've found the connector wires were installed wrong and the motor would run in reverse. You can check this by first checking the rotation of the old one, then swap over and plug the new one in, turn the blower switch on and see if it spins in the same direction as the original. If it runs backwards, hit the release for each terminal in the motor connector, slide both wires out, then reinsert them on the opposite sides.

On top of the blower box is a lever with linkage that runs through the firewall, this is the linkage that operates the blend door. If you remove the glove box door, you'll be able to access the linkage where it connects to the actuator. If you release the rod from the actuator, you can then manually operate the blend door by moving the linkage.

 

Wow, I would have never thought about the polarity being reversed. The one I pulled off has butt-splices at the connector. I wonder if It was found to be spinning in the wrong direction and the previous owner found splicing easier than releasing the pins on the connector. If so, that makes a little sense as to why the fan cable had a butt-splice in it.

I'll check on the mechanical connection to the blender door. I was hoping there was a way to electronically stimulate it so I could test the whole thing in one shot.

Thanks again,
Matt

Hey guys,
I'm still waiting on the new blower to show up, but I did clean the evaporator coil and tested with the old blower. It still seems like the air-flow is pretty weak. Here are some pics from the clean out. Some trash and some leaves and some hair.

Any idea where I can put in air filters to help prevent this in the future? I think this grate below the (photo below) is where the recirculated air comes in. What about the fresh air?
Thanks!

 

Still wondering about where the air intakes are so I can rig-up some filters if there are any suggestions from the community.

In the mean time, I replaced the blower. I wasn't able to crank it up because I had other parts pulled off. (I have to work in small spurts since I have a small herd of kids to take care of! haha).

I did turn the key to on to check air flow. It blew like a mad man... out of the defroster... Is that expected with the engine off (i.e. no vacuum) or is the blower backwards like @HeyYou mentioned above or is the flow selecctor broken now?

Thanks in advance!

 

Vents are all vacuum controlled, and default to defrost, so, engine not running, yep. Defrost vents.

 

Thanks @HeyYou ! It was easier access if I needed to rewire the blower with the alternator out. I’ll get that puppy back on and go for a test drive asap!

 

Now that it’s cooling down here in Texas… it’s blowing like a champ! That blower must have just been getting weak.

We’ll see the next hot day if the new compressor and old evaporator can keep up with the improved airflow and be a fully functional air conditioner!

Thanks y’all for all the help!
