The Nissan Path

Moved from Washington to Arizona, drove down in my 05 pathfinder and pulled a u-haul trailer. Before I left i had my A/C unit checked for leaks and charged, they recommended i replace the fan clutch so i did that. About an hour outside Phoenix my A/C stopped blowing air. The rear kept blowing which kept my dog cool but did little for me. Did some research and replaced the blower motor and resistor. Blower motor is OE but the resistor is not. Started blowing air again but would randomly turn off and on. The harness to the blower motor seemed loose so i replaced that. Still didnt fix the problem so I changed the relay thinking that would solve it, no dice. After driving around all day and playing with it I have realized that it blows A/C and heat no problem on any speed except the highest setting. When turned to the highest fan speed it kicks off in about 3 seconds. Anyone out there experienced any issues like that? Wondering if i could have picked up a bad resistor?

Thanks for the help!

If your electric fan motor is defective the ECM will cut off the AC compressor. Once temps. drop as you move it will start the compressor again. happens more frequent in stop and go traffice. This Happened to me as I noticed the fan motor was starting intermitently as I would bump it on top with my hand.
