My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
Check the engine coolant fan (if electronic) and see if it is engaging when the ac is running especially when the ac blows hot.If it is not this can be an issue with the fan itself,the control relay for it or the engine computer needing further testing to locate and repair the fault here.
If this is o.k. let me know so we can continue,thanks Pete.
