Hey everyone, sorry if this is redundant. I know there are posts out there dealing with blower motor issues but I spent some time searching and can't find all the info I need. Leaving in the morning for St. Louis and really would like get this fixed.

I finally got around to adding more refrigerant to my AC system to get the rear blowing cold. All was going well and both front and rear were blowing cold, but then the rear blower quit working. So I turned the van off and went to reset the blower relay.. but I still had the key in the accessory position and got some sparks. Turned the key off and reset it again. Rear blows just fine, but now the front motor will not come on. There's another relay to the right of the fuse box that I thought controlled the front blower, so I reset that as well. But still no blower.

Can someone link me to the thread that identifies all the relay's and stuff under the dash?

It looks like I should be able to replace these right? But I can't get them out. Thought I'd pull one from the parts van and test.

What type of damage could I have done?

Also, there was no smoke from under the dash or electrical smells like I burned any wiring up.
