Hi All,

I have a 2011 RX350 and I need your help. Long story short I was trying to replace a noisy blower motor but some how I managed to break my AC!

Now the wiring harness supplying the blower motor is missing the +12V. I checked the 10A heater fuse under the driver side cup holder and its fine. I checked the ground pin on the wiring harness and its grounded. The wiring harness itself looks fine. (no broken wire)

Where does the +12 V come from? What do I need to replace?

If anyone has a wiring diagram it would be much appreciated.

$15 for 2 days of access to all the manuals.

Tech manuals are a no-no in this forum.

I was re-posting from one of the moderators in another thread and just being helpful, I think $15 for access to all the data is not a bad deal compared to repair shop rates. I also think few members have a service manual as few work on our own cars. I don't and do most of my own work.

Have you checked all the fuses? It may not be the one you suspect. Also relays. The owner's manual may have some guidance to narrow your search.

 

I just thought there might be a chance someone have been through this before and could save me some time.

My understanding now is that there is a fuse and heater relay between the battery and +12V going to the blower motor. I will pay $15 dollars to get a confirmation. But that may not solve my problem.

I will recheck the fuse again. Thanks for trying to be helpful
