We are only allowed to diagnose one concern per question, which would you like me to address and which liter engine do you have?

I replied last night for you to just address the ac but received no response.

Thanks, ***** ***** is no vacuum getting to the HVAC control it will default to defrost. The engines intake on the 5.4 creates the vacuum and stores it in the reservoir. We need to check and see if the reservoir is storing vacuum or losing it using a hand held vacuum pump with gauge. While running you should see over 15 in hg of vacuum. Below are 2 files showing what the reservoir looks like under the evaporator so you can locate it and its line, also the schematic showing how the vacuum gets to the HVAC.

You want a excellent 5 star answer & I would like to be rated the same for providing it. Consider I don't know your skill level & I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies. Try your best to respond with good detail so I can do the same. I normally log in at 3pm and work late. A rating is required. Your rating me, what I type. I am not an employee of this website, nor have control over the fees or the time it took to get a response. If you rate negative or not at all you still paid, but I get nothing. I want you pleased with me and my efforts, so let me know if your experience here has come up short.
Thanks Chris

You will have to buy or borrow one or try to visually find a leak.
