Had to remove the washer fluid reservoir in order to get the blower motor off but it only has two bolts so no biggy...

I was having a problem with my Max A/C setting. When i turnd on the max setting the air flow would cut in half of what the normal a/c setting was. I was reading on here last night for some tips or answers to my problem. I found a thread where a guy had a tacobell rapper stuck in the intake. So i poked my head under the glove box and wouldnt you know it. I found a plastic grocery bag stuck in there. I removed it and i was "blown" away. Just another reason i love this website!!!!

Another question...when I pulled the fan out, I could see thru to the bottom of my truck. I know this is the fresh air intake...but...the a/c was left in the max position when the key was turned off. Wouldn't the flapper have stayed in the max position, thus I couldn't have seen all the way thru. I almost always run the a/c on max, so all the junk collecting in the evap coil kinda puzzles me.

I was telling a mechanic friend of mine about your problem of not being able to see much of the evap coil and he showed me a can of coil cleaner called "Cool-it". It comes with a fairly long piece of small diameter tubing that you connect to the can and use it to spray around inside the blower box. He said the stuff dissolves the lint/dust coating so that it just drains out the bottom. Also said it leaves the ductwork smelling great! He also said that he sometimes has to drill a small hole in the box in order to spray the entire coil....

this wold be an avg of 5-9 hrs on most vehicles.
so unless it is leaking... definetly clean the fins on the evap core first.
