hello guys i am new to this forum. i have a 2007 toyota sienna and my manual A/c and hot air panel stop working and not even lighting up. i checked every single fuse i could see and they are all in working order. i am stuck and have no idea where to keep looking at? i read some stuff online on a/c relay but i dont know how to check if still working. any input would be greatly appreciated thank you

If I remember correctly, the AC relay and horn relay are the same. You can switch them and see if it works.

The A/C Relay is for the Magnetic Clutch (for the compressor), doesn't have anything to do with the Panel. OP, did you check all of the fuse panels? There are 2 inside and 1 under the hood.

There are multiple fuses (6 in all?) that feed various parts of the AC system. Most are shared with other car functions, so their loss would be readily apparent as other things would also stop working. But there is a hidden little fuse holder to the right of the cabin air filter (behind the glove box door) that only seems to control the AC dash controls. I'd start there as it's likely you haven't checked this yet.
