1994 Rear AC Blower Fans Not Working

[mocne]

On my 1994 Previa the blower fans for the rear AC aren't working when I switch the fan on, however I do hear noises from the overhead evaporator and the fins on there are getting cold when the fan is switched to on. I have removed the cover from the rear AC unit and found two 5 amp fuses that are good, but I do not know their function.

I have looked for the main fuse for this system in the FSM but can not find any information anywhere as to the location of this fuse. In our owners manual there is a reference to Fuse 29 which is a 10 amp fuse but no location is given. From the information I found online I think the relay for this system is on the RHS by the heater core but there are several connectors and relays there which I'm not sure about.

Can anyone guide me as to how to get the rear AC blower fans going?

The only thing I've ever seen anyone do on the rear blower is this https://www.toyotavantech.com/forum/showthread.php?8804-Rear-AC-fan-Blower

You're in no man's land too, I guess

Thanks for finding and linking that post, unfortunately this doesn't seem to be the issue with mine. My motors dont even try spinning at the moment. I'll try to test the various voltages coming into the switch, relay and motors later in the week. If I figure something out I'll post.

Nope, I know, it was just to illustrate the only rear AC thread I ever recall seeing. Please let us know what you discover, because the next person who needs it may be me!
