How many relay switches does the ac unit on a Chevy S-10 1995 have?

The 1995 Chevy S-10 AC system doesn't use relay *switches*. It uses relays, which are electromagnetic switches, but they aren't typically called "relay switches". The number of relays in the AC system can vary slightly depending on options (like an automatic climate control system), but generally, there are two main relays involved:

* AC compressor relay: This is the most significant relay and controls the operation of the AC compressor.

* Compressor clutch relay (sometimes integrated): Sometimes this function is combined with the AC compressor relay, other times it's a separate relay.

Therefore, you could say there are either two or one (if combined) relays in a typical 1995 Chevy S-10 AC system. It's best to consult a wiring diagram specific to your vehicle's options to be certain.
