Blend Door Actuator Problem

Hi, I have a 2009 Grand Cherokee Limited and I had the typical clicking coming from the HVAC actuator just behind the glove box. I ordered the part and it arrived. When I put it in, it did not actuate. I put the old one back in and it actuated and clicked. So I figured that the part was faulty. I got another part and installed. I have the same result, it has not actuated at all. Previously (with clicking actuator), if I started the jeep it actuated, or anytime that I switch the fan on or off. With the new parts, nothing.

I know there is a calibration process which each I find online have not worked. It has the auto climate control. If someone knows the calibration process I would appreciate some insight.... or maybe someone has had a similar problem.
Thanks
Chris

Calibration for the automatic climate control has to be done with a Starscan. The procedures you've found online are for the manual temperature control system.

I haven't heard of people putting a new one in and not having it work, so I can't help there.

Re: Blend Door Actuator Problem

My Autel DS708 will do the blend door calibrations but, on mine even with the calibration, I still get a code for excessive travel. I know this doesn't address the clicking and inop. new actuator but, if you can find an independent with a good computerized diagnostic tool, you might be able to have them check it out for less than the stealer might want.

Re: Blend Door Actuator Problem

Well I found out what the problem was, the plug was not seated correctly. Once I forced it in, it worked fine.
Thanks
