Radiator fan isn't working the way it's supposed to. I dismantled the compressor, the condenser, and the a\c lines. I replaced the alternator belt with a new shorter belt, and car starts and runs. I saved the electrical connector of the R-134 bottle because: When this connector is unplugged from the circuit, the radiator fan, and the condenser fan turn on and stay on when engine is started. But when this R-134 connector is unplugged from the circuit, the fan(s) never turn on. My next step: I took out the fan #3 relay ( this relay is definitely required if the a\c system is to be functioning), and nothing changed. I have a hunch that a jumper wire somewhere at the relay box may be all that's needed to remedy the problem. Thanks for your help. If it makes it easier for you to give me instructions, I have access to Alldata. Com for the rav4.
