A couple of weeks ago, I took my 2002 Windstar in to Jiffy-Lube and got the standard oil change/lube job. As always, they tried to upsell me on air filters (the big cone one in the engine compartment and the oblong one in the passenger compartment). And, as always, I turned them down.
That night, as I was driving to work, I noticed a clicking noise coming from the area around my heater controls. and the next morning as I drove home from work, I noticed that the heater isn’t working. The clicking noise is regular, and does not change frequency as I change the speed of the fan.
Is it possible that the Jiffy-Lube people didn’t properly re-install the cabin air filter? I’m going to go there today and see if they’ll check it out.
