How to fix air conditioner problem in 2006 F-250?

You can probably have a custom tuner change the feature in the PCM programming so you cut off the AC at a higher throttle position or not at all. You can do it yourself with a switch to the AC WOT cutout relay and save at least a couple of hundred $.

What are the problems with my 2006 F-250 diesel?

I bought this truck new in October 2006 while in Nebraska. First REAL test of air was while I was in southern California april-june 2007. I have two different problems. 1) takes LONG time for the air-conditioner to cool down vehicle. if outside temp is 90F or above the vehicle does not feel comfortable until I have driven roughly 25 miles.

Where is the temperature controller on a Ford F-250?

Automatic Temperature Control-equipped dual zone trucks have two; the second actuator is low, located above the transverse air duct. Does the temperature controller work? The related article below provides instructions for testing the manual controller, a simple potentiometer.

How many AC compressors does a 2006 F-250 have?

It ought to be able to pull 20 ac compressors and not notice them. There’s about a 50% possibility the 2003 truck has a 7.3 diesel in it, in which case, it’s got an infinitely better motor than the 6.0. I’ll stick by the statement that a longer than average time to cool the truck down is somewhat normal in these newer trucks.

Why does my Ford F-150 blow only hot or cold air?

The heater core is buried deep, but you can feel the entry and exit hoses. Hot water in, hot water out, then everything is fine. If not, your heater core may need back flushing. (Related Discussion: Before replacing heater core – www.f150online.com.) Step 2 – Does the A/C work? Figure 2. Check the coolant temperature sensor.

What to do when your car heater is blowing cold air?

Start the engine with cap still open and let the engine idle for a few minutes. If the coolant level should drop as the thermostat opens, top it up as necessary. This should bleed off the air bubble. When the engine is fully warmed up, put the cap back on and take a drive to see if the heat output has returned.

What should the core temperature of a Ford PowerStroke heater be?

GO to H4 . REFER to Section 303-03 to check cooling system function. Using a suitable temperature measuring device, measure the heater core outlet hose temperature. Is the heater core outlet hose temperature similar to the inlet hose temperature (within approximately 6-17°C [10-30°F])?

Why does my car fan keep blowing cold air?

Engine fan: Most vehicles today have a thermostatically controlled electric fan that comes on when additional engine cooling is necessary. A defective thermostatic switch could make the fan run continuously, reducing the coolant temperature to the point where you can’t get enough heat into the interior.
