Wow, this little truck of mine never ceases to keep me on my toes! Its latest trick? For weeks now, I’ve been getting the following sequence of events:
-driving along smoothly or idling at a street corner
-engine revs and truck jerks
-repeat about every 30 seconds
Yesterday, I finally figured out that this has been happening only when it’s hot out, which gave me a clue as to where I should start my diagnosing.
I went out this morning, popped the hood, idled the truck, and played with climate control knob.
As it turns out, the AC clutch wheel thingy that hasn’t been turning to provide me with cold air has suddenly decided to TRY to turn. It will click, spin part of the way, rev the engine, jerk the truck, and then quit. This will happen in all climate control positions except off.
I’m detecting a theme here. Except for the first problem caused by low oil, every issue with this truck has had to do with the climate control system. I must have known deep down in my bones that I was having another issue in this area because it hasn’t caused me to worry much about the truck and I haven’t hesitated to take it out. Now, I know to roll down the windows and leave the air OFF.
I found a great Ford forum with really helpful folks and they are helping me work through this. I’ll troubleshoot as far as I can on my own, then go to a pro… once I’ve had the brakes done. That’s not urgent, but it really does need to get done before I get back to SK and start doing long hauls with the truck.
It’s a shame it’s so nasty cold and windy out today even though we got the promised sun. I was going to take Moya out for a much deserved wash and wax.Share on Facebook
