I had 16 acorns in my blower motor today. Question. Is how do they get there? I understand from the fresh air intake under the cowl. But how is a rodent getting under the cowl?

Any ideas on what I need to plug up?

 

Wide open under the cowl unless you place a screen over it.

 

It’s a pretty open path under the cowl…and rodents can squeeze through some disturbingly small holes.

 

I could not see how a rodent gets under the cowl, but I covered it up regardless. The bolts holding in the duct seemed made for holding down wire.
The #7 fuse was blown, I replaced that.
The blower will run for a fraction of a second when the car is first turned on, it is not longer blowing a fuse. The motors feels smooth, no obvious cuts in the wires.

Any ideas on why the blower will not run continuously?

 

I put in a new blower, same symptoms. the motor will work if I jiggle the wiring under the dash, so I put it back together semi confident I found the issue. Once it was bolted in, there was no amount of manipulation of wiring that I could do that would get it to work again. I did notice that the wiring harness below with the larger gauge wiring was getting very hot. The red/black to brown/black connection. Does anyone know what that is? It appears to go into the the blower motor housing. Could that be the resistor pack? I thought when those failed, only high speed worked?
Rave electronic, has it as a C015 connector, but does not show where it goes.

Any ideas are appreciated.

 

Given the blower will work at high speed for a brief moment when it is first plugged in, and will run at high speed sometimes, Both the new one and the original perform the same way. I am thinking it it the resistor. I found a video on repairing it, but once I got it out, it did not look like the one the on the video. So I dont think I am going to tackle repairing it.
The Denso part number, 077800-0700 does not pull up anything in an interchange or other google searches.
It has the same part number as a Jag. Denso 077800-0700, mostly seems to pull up Jaguars, which makes sense.

Heater Blower Resistor 04-09 XJ8 XJR

Question is that if I am bench testing the resister, gong across two of the terminals I get no reading, on the third I get about 2.2. Of the four terminals, leaving one probe on one terminal and testing the other three.
It sounds like that indicates the resister is bad. Am I dong this correctly, electronics are my most limited skill.



It looks like this one will fit, despite being for a Honda.

I will see if I cant find a used one, it is pretty easy to access actually. I going to put it back in head head screws, much easier to work with than philips head screws.

 

I think that the fact that it worked when you jiggled the wires indicates a poor connection somewhere in the dash. My D2 had a couple of very badly corroded plugs in the area above the front right foot well.

 

I was not able to replicate that very well. I will keep looking, but the resistors seems to test bad regardless. The 2nd time the squirrels got in there, there was an electric type smell before the blower quit. There is also hair all over the wires, this is not as much fun as you might think.

 

Turns out the resistor failed. I wonder if that was the smell when it failed last time. I got a $35 part on ebay that tested and works fine.

 

Good news
