Comfort Eagle Posted June 28, 2009 Report Share Posted June 28, 2009 Hey guys, Just finishing up some details on my 78 Stanza/510,and I noticed the interior fan only works on #3/high. I am guessing it is a resistor pack that is bad,but where is it on this car,and is it easily replaced,or do I need a new blower fan? The good news is the AC works great!!!! Quote Link to comment
yello620 Posted June 28, 2009 Report Share Posted June 28, 2009 If it is working on high, that means that the fan is working and should not need replaced. The lower speeds go through a resistor that is a common fail item. I do not know where it is located on your car though. On a 620 this resistor is common to have a wire that comes off. It is located on the drivers side of the heater box-up high with two wires going to it. If yours is a three speed fan, then you will have at least three wires to it. Quote Link to comment
datzenmike Posted June 28, 2009 Report Share Posted June 28, 2009 I think the 620 one looks like this: http://i138.photobucket.com/albums/q251/datzenmike/Nissan%20Electrical/electrical620heatertwospeedcoil.jpg[/img]"] The fan is on the right side, beside the heater assy. Look just above the fan motor and very slightly to the left on the blower housing. The resistor has two screws holding it on with terminals facing outward and the resistor coils inside the blower to keep them cool. Quote Link to comment
Comfort Eagle Posted June 29, 2009 Author Report Share Posted June 29, 2009 I think I found it,but there are maybe 4-5 wires on it,and no screws holding it in,so I have no idea how to remove it. Quote Link to comment
datzenmike Posted June 29, 2009 Report Share Posted June 29, 2009 Some snap in like the one pictured above. Quote Link to comment
Comfort Eagle Posted June 29, 2009 Author Report Share Posted June 29, 2009 So if I can snap this thing out ,where can I get a new one? Is Nissan my only hope? Quote Link to comment
datzenmike Posted June 29, 2009 Report Share Posted June 29, 2009 You may be able to cobble it back together or get a resistor from some other vehicle and attach it. I can look up the pt. number later? Quote Link to comment
