A/C Blower cutting off problem solved?

[SHAKEDOWN]

Some of you might remember I had posted a spotty problem with my fan/blower cutting off by itself. Others have too. When it happened I would have to turn off the fan and then turn it back on and it would work fine. I could never get it to repeat itself for the Dealer. This started happening just a couple of weeks after taking delivery in May of '05. It would only happen, as I recall, when using the A/C. Finally, the other day I was sitting in a parking lot with the A/C on and the fan quit without any imput from me. I was a couple of miles from the Dealer and I took it to them so they could observe it happening. The tech, after putting a tester on the blower control, said it was the resistor in the "Variable Blower Control Module" located under the glove box. It is a $56.95 part. Part number 27151-5Z000. It is an easy install. Just two screws and the power plug. Hope this helps you other folks who have the same issue. Time will tell if this new module will permanantly solve the problem. I will let you know if it happens again.

The fan in my Xterra recently started only working on level 4 (high). Turns out this is a common problem with the Xterra & the solution was the same as yours. A new blower resistor. It was a $25 part & took 10 minutes to replace. Location was also under the glove box. Works perfectly now.

Thanks for posting this. My truck has done this a few times.

It usually only does it after driving long distances. It happened three times on a trip from Colorado
To Texas.

It's been eight months now and the problem has never repeated. Looks like the new module is the permanent fix.

I'm glad you got it straightened. This will help out others with the problem.

Do you know if the module had three fins or five. The five fin is the fix for the problem. The old dealer stock may not have been upgraded yet. The three fin did not have enough surface area to dissipate the heat from the power transistor in the module.

thanks alot mine does the same thing i am on my way to the dealer now

New module has five fins. I did not think to look and count the old modules fins.
Did not think about the heat disipation either but it makes sense. Good point.

Tried it today and my a/c was still broken. This makes the 3rd repair attempt. They are sending someone from Nissan to check it out now.
