1995 Cadillac Deville Blower motor

I don't believe that info from Docfixit will help now. As I stated I removed the blower already, so I disconnected the negative battery, that will erase any codes correct. There must be a way to check the blower while it's on the bench? Are you telling there is absolutely no way to check it this way?

One other thing I forgot to mention, before I removed the blower, I did that test with the on board diagnosis, don't know if I had to go further with it, anyway I didn't, but this is the results I got.
PO98 Histiry
1039 current speed sensitive steering signal fault
1052 History keep memory alive
No ACP codes
No SIR codes
No TCS codes
Is this of any help, cause like I said I diconected the battery, so I'm sure it's all lost now.

Thanks Doc, I've already tried that, ( no spin). Today I tried just laying the blower on the top of the engine, with the fan blades facing up. I then installed the 3 pin plug from the vehicles harness, hook the battery back up & turned on the blower swirch, (on Hi) with no results. I then took a test light grounded the pigtail wire & probed the red wire, (note the harness plug is still hooked up to the blower)I had power. I then back probed the gray & black wire with the test light, the motor gave itself a small spin then stopped.
Now from what you just told me, when I had the hot to the red & the ground to the black, then grounded the gray & black, it should spin, right. So if I'm reading you correctly, the motor is NG, correct. I appreciate your help, & thank you so much.

Thanks Doc, I was afraid it might be the programer, but what gave me doubt was, the programer was moving the mix rod for the duct & I was assuming the rest of it was ok. I guess I'll pick up a blower motor. One other question I have (if you don't mind) I had to remove the front engine mount & lower the engine to get the blower out, after removing it, I noticed I could remove the 3 small bolts in the black plate & pull the plate & the cover under this plate off. It now looks like, if I had done that there woul have been enough clerance to remove the blower without disturbing the front mount. My question is, is this correct. I'll get back to you after I replace the blower. I hope that takes care of my problem, this has been a nightmare for me, as I'm doing this job as a favor for a friend of my wife. Seems every time I do someone a favor, I run into the biggest problems & tie up more of my time than expected.

Hey Doc,
I just purchased a used blower motor on Ebay, got it today, checked it out, just as you advised, spins like a top. Installed it and it works great, thanks for the help, guess I'm never too old to learn a new trick, again thanks.
