A/C Blower cutting off problem solved?

[Mychael101]

Appears that there is a new redesigned control head that will be available. Its being put on tomorrow at 10am. They say its a 45 minute job so I should have the initial results up by noon. Either way I'm going to exercise my rights here in Texas and file a lemon law complaint.

sweet. Mine has done this a couple times. I will check to see if mine is the 3 fin unit.

Many thanks to SHAKEDOWN! My VBCM (Variable Blower Control Module) was THE CULPRIT! I replaced it and my problem was solved =)
A lil more info regarding my specific scenario:
I have a 2005 Titan. I first noticed my problem a couple of months ago. It started one day when I had my heater on around mid-speed and I noticed that it dropped to a lower speed. I then turned it to hi and it worked just fine. A few days later, it would only work on hi and no in between. About a month later, I went to use my A/C and the problem was still there, but then it started to turn off at the hi speed too. At times I would just put it at the mid-speed mark and it wouldn't do a thing. I'd leave it there for a few minutes then it would suddenly come on at the mid speed rate.. Then it would just shut off again. Eventually, it progressively got worse. At the hi speed, it would just turn on-off-on-off, etc.
My old/bad VBCM was a 5 finner. I replaced it with the 27151-ZM70A that I bought at the local dealership for $61 bucks (couldn't wait to buy it from an online seller, too hot here in Texas). It was a 3 finner! The 5 finner had small fins that are very close together. The 3 finner has coarser fins the have larger gaps. The 2 screws holding it in place are 7/32. Took me about 5 minutes to make the swap! I'm now a happy camper!! =)

Called to get a quote from a local dealer and gave him the part number.....

"$169 and in stock"
"$169?!"
"Yup"
"Ok, thanks. I might call you back"

Called back about 10 minutes later just to make sure I gave him the right part number....

"Hi, I just called a few minutes ago and wanted to verify I gave you the right part number"
Without even letting me get the part number out "I already gave you this information, your number is right" (in a sh*tty tone)
"Thanks *******" click

Just ordered the part online from Nissan Parts Connection for $55.72 shipped. Hopefully it solves the issue.
