I looked at the fuses they all look good if it is the control head how
would i check it ?

Hey Bob,

You must check the power and ground input and outputs of the system, here is a complete wiring diagram that will show you how to test the controller and the wiring.

I put a new automatic temperature control head in now it lights up ran a diagnostic test and no codes came up but still no heat

check to see if blend door is getting power but it may be a sensor that is screwing up that is why you need to get it scanned for codes.

How do i change the blend door unit

sorry I gave you the wrong instructions for resetting actuator see pic also covers getting codes if not the actuators

for somereason I can't add images to say what to do

ok now have pics

can you show me what a in car ambient temperature sensor looks like please which is behind the right bezel thank you.

see pic it's a two wire connector

Hey Bob,

I found these images for you to show you where the blend door actuators are.

Please let us know happens so it will help others.
