there is no ac/heater blowing at all, very small amount of heat coming out of the defrost/regardless of setting, checked fuses, and they were fine, there is a clicking sound like it wants to work, but it doesn't, however it was working in the morning, but went to lunch and nothing, do you have any suggestions of what might cause this problem and were do i start,

Thank-you in advance

If no speed works, I would say either the relay is bad or the motor itself is bad. WHat you need to do is check to see if the motor is getting power. If it is and doesn't work, it's bad. If there is no power, then I would check the blower motor relay and resister. Neither of which are expensive parts.

Let me know what you find and if you have other questions.
