You disconnected the steering wheel to remove the blend door actuator? ?

So, my 2006 Ford Ranger is stuck in one temp selection - thank god it's on a warm setting but not hot. If I had to guess I would say it's around 70 percent heat. I purchased a new blend motor from Advanced Auto for $40. I pulled the old one, plugged it back in, turned the key on and adjusted the temp selector - nothing happened. The old motor didn't move. So, I plugged in the new one and got the same result. I found an electrical diagram and started checking the wires. My resistance from warm to cold was 4800, my readings from center point to each of the warm and cold settings ranged from 185 to 4800 so that part seems fine. With the key on, I check for voltage at the plug and had 12 volts. I checked the power to frame and got 12 volts. With the key off I get 0 ohms from ground to metal frame. It seems like everything is checking out fine. I'm guessing that this point I bought a faulty blend motor from Advanced. Am I missing anything? All 5 wires at the connection behind the glove box seem good to me. Any thoughts?

OK, the information for testing the wires says the resistance should be between 5000 and 6000 for the total loop and mine is coming back at around 4840. Does anyone see this as a problem? Ford says it should be between 5K and 6K, I don't think 4840 is that far off. Also the range the testing documents call for center point to warm or cold should be vary from 250 ohms to 5500 ohms. Mine ranges from 185 ohms to 4840 ohms which I don't think matters that much. Any thoughts on that?

Update - 12-29-11. I returned the actuator that I purchased from Advance. Turns out it was defective. If it wasn't defective I would have saved about 6 hours of my time testing and trying to find another reason why it didn't work. That 6 hours of learning was a good thing. I now understand how the whole system is suppose to work so I guess overall it was a good thing that it was defective. Anyways, I guess if you take Ohm readings and they are at least close to what the specs say they should be, then you should be good to go. I bought the new one from Auto Zone for about the same price ($40). Putting the back screw/bolt back in place was a pain but I did manage to get it done. It's nice to be able to adjust the temp in the vehicle again. Thanks to everyone on this forum with their helpful comments and stories.

Save yourself some time and avoid the blend door unless you have to.


How does one flush the heater core?

Thanks,

I have a 98 Ranger s/cab 3.0 auto. Heater would not get warm-checked hoses-inlet to core hot-return was cold, Heater seemed to work fair until I drove it about 5 or 6 miles then it would cool down. I took it to my friendly Ford dealer and they flushed core, same thing, Then I took it to a recommended radiator shop, they flushed it, same thing. SO-thought I would use a little shade tree work, what did I have to lose. I went to parts house and bought 12 ft of heater hose, I already had a boat bilge pump. Put pump in bottom of 5 gallon bucket, attached hose from pump to heater core and other hose from core to bucket (return). THEN I put 2 gallon of white vinegar in the bucket and attached lines to battery. Flushed for 30 minutes, switched hoses and flushed another 30 minutes. Then to be safe I emptied vinegar and did same thing with tap water. Guess what----Now I have plenty of heat. I was just about to have heater core replaced (400.00+) so the old shade tree job saved me a bundle. I hope this helps someone else before they invest in core replacement. ON the 98 the steering column and dash has to be removed to do this.

The inlet being hot and the outlet being cold is a dead ringer for a clogged core. Good job on recognizing it and fixing it for free.
