I want to know how I can trouble shoot fan blower problem get it behind me?

Im still struggling with the fan blower ordered a new fan blower one like the factory one i talked to a Nissan tech and he told me that the after market fan blowers can drawl a lot of power so i ordered one close to the factory type. The one i have now i turn it on the first three settings and nothing put it on 4 and the motor will come on for a split second and pop.I was wondering if a relay could be bad i dont want the same problem when i install the new one.

Your talking about the interior blower? If the first 3 settings don't work, you have to replace the blower resistor. The relay is a different story. Though the relay could be built in the resistor. I'm thinking this is not your case. The resistor controls the speeds of the blower, until it gets to high. Then the relay kicks in to give the blower full power. I would say replace the resistor. I good thing to remember is, If you get any speed from the blower, the resistor is bad. If you get nothing,check the fuse, replace it, if it blows again, replace the blower. If the fuse doesn't blow, then start looking at the controller and wires. This advice goes for all makes and models.

I need to know the location of my blower relay. Already changed out the blower resistor, that did not remedy the problem (fan will not come on). Yes, I installed it correctly.

The blower relay is for high speed fan only most of the time . Do you know how to test electrical circuits ? It sure cuts down on buying unneeded parts . Here watch this video , this is a Chrysler vehicle . Don't know what you have , doesn't matter . They all work pretty much the same . I suggest you watch a few other trouble shooting videos as well .Is Chrysler Blower Motor Test subscriber requested video This next vehicle is a GM product , this one uses a relay for high blow only .

Trying to trouble shoot before I buy a resistor. Why does the heater/AC blower fan work only on 1,2 or 3 but not 4 high Does it sound like it could be the blower switch and not the resistors?

This part is just behind the glove box and appears to be easy to remove and inspect. You might try that first. If the part is bad you should be able to see the defective component like a burned resistor or other electronic component.

Trouble shoot heater fan on a 1996 Plymouth Voyager Van

Check for 12 volt power to resistor under dash on passenger side. Follow wires from under glove box (from blower motor) to resistor, which will be where wires are connected on duct work. You should be able to test for 12 volt DC power there.

Hi Tim, The resistor is fitted into the fan housing behind the center consul. to get to it, remove the side kick panel and follow the cables for the fan. Disconnect the plug and remove the screw holding the unit in place. Remove the defective unit and fit the new one. Reconnect the plug and refit the panel. Enjoy the breeze. Regards John

A t600 kenworth 2000 model the blower motor only blows on high is it the resister

Yes - you diagnosed the problem yourself. The classic symptom of a heater that only blows on the "High" setting is a burned out/damaged or otherwise inoperative blower resistor.
Replacing the resistor should return the two missing blower fan speeds.

My heat and air blower will not turn on it just stopped a few days ago which means my defroster doesn't work... how do I fix this?

The fan, which is the "air blower" for heat and A/C sits on its end in the heater box which is just above your front passenger's feet. It could be bad if it is not running when you turn on the fan switch. These cost about 50 bucks and are available at any parts store. Fairly easy to replace, disconnect the wiring plug, back out some screws, vacuum out the hole, reinstall in reverse order. Note some trouble shooting should be done to eliminate fuse and switch as bad guys.
