Help! Rain Sensor Chip

My first thread. Well I noticed that my rain sensor doesn't work becuase the wipers don't function when set and the automatic lights don't cut off during the day. I took off the rls and noticed a rattling noise. I open the els and something fell out. Can anybody help me as to where the fallen piece should be soldered at.

Fallen piece has "151" on it

Thanks in advance.

I have found 3 pieces with 151 on it but there could be more, the problem is that you can't open it further without desoldering a few thing.

Here are the pictures.

Thanks for your help. I had those three as well attached as well, none on the back however. I noticed in your picture and on mine that solder residue is on where a fourth could possibly be. Anyways, I gave up on trying to solder it because the spacing was small. I'll buy one.
