Hello my name is ***** ***** welcome to just answers! I will be assisting you with all of your vehicle questions today. Give me one moment while I review your question and come back with a answer. Please be aware I do not know your skill level or abilities so I will be asking a lot of questions and in a lot of cases we will respond to each other quite a lot before we find a solution. As far as phone calls are concerned that is the system prompting you, not me, and they do cost more money, I prefer text but in some cases a phone call is required. If I don’t answer right away or quickly in conversation I am helping another customer or have stepped out for a moment and will respond as soon as I can. Ok lets get started!

Hi welcome to just answers my name is Ricardo. Start the engine and turn the air conditioning system on. With the fans rotating at low speed, ground the Green/Black wire and check to see if the fan comes on high speed. If the fan comes on to high speed, check the engine control module control of the relay. Use a scanner to see if it shows the relay is on.

Expert:  Ricardo Hohl replied 1 month ago.

If the radiator fan does not come up to high speed, bypass the number two fan relay by jumping terminal 3-5. Check to see if the fan operates at high speed.

Hey Ricardo....you mentioned fans in your response above and also to ground the green / black wire to see if the fan comes on at high speed. The Corolla only has one fan and only has 2 wires going to the electric fan motor so I do not think it is a 2 speed system. I thought the 2 speed fans always have 3 wires going to the fan motor. Am I correct in my thinking?
I am still not near the car yet. Other life events such as moving have set this on a back burner.
