Default code 11 and 21 on A/C switch 2001 model

code 11 is room temp sensor. where is that located?
code 21 is from being in the shop.

There is not much expertise here for the Gen I Prius. There were a couple of members who were quite knowledgeable on the Gen I, but they moved on several years ago.

I have a 2002 Prius, but I am unfamiliar with the sensors and codes you describe. -- Sorry.

Unfortunately, many infrequently encountered problems must be referred to Toyota dealers; as most repair shops have no experience with early model Prius's.
