Looking for compatible replacement FETs for a Automotive blower motor resistor

[BrianJ]

I have 2 different components:

2 Rectifiers (p/n 5105, to-220 style )
2 Rectifiers (p/n 4101 EC, to-220 style)

I believe one of these components are bad, in addition to the possibility of 3 large capacitors being bad.

The board these belong to is similar to:

Airtex-4P1581

I have more time than money now and I know a few compontents wont cost me $120+

Any help finding the parts would be much appreciated.

Can you take some pictures for us. Nice and close and clear taken in a well lit room.
Thanks

Here are some, I know not the best but it's the best I could get. I'll try taking some outside tomorrow.

Thanks for the photo's. The only thing I can find is a MCR506 which is an SCR but no sure, similar case which might have been updated from the TO-220. Can't find anything on the other part. This is a real mystery, someone else might have another idea of what they are. I'll keep looking and let you know if I find anything.

Thanks, I appreciate your help.

I just realized what caused this board to die was the motor shorting. Before I wasn't sure if it was the board just dying of heat or unclean power but it seems now it was feed back from the motor starting to short.

In that case I suppose the Rectifiers are the main problem and not the 3 large capacitors?

(I'm still working on getting pictures of the whole board)

Below I've attached the pictures of the board. Thanks in advance for you help
