2005 Dodge Caravan front blower (fan for AC and heat)
first, thank you for all the post, even ones that didn't get solved. My front blower went out today JUST after I got on the road home. Read the posts here and here's what I did..
Removed opened the glove box and pinched the left and right sides in, then you can flip the glove box down out of the way. I didn't see the fuse right away (Part #172KR1 7502), but I had bought a new blower anyway ($100 Advance Auto, squirel cage design), and seen the same 14 gauge wires from the new blower going to what looked like a connector. I was going to remove the connector (two plugged in here, blower wires are on the right, only two wires), but noticed a crackling sound when I touched the wires. The I seen a bulge the the plastic the blower connector pushed into...it had been getting very HOT. The power wire fell off in my hand, and the connector was in pretty bad shape from high currents here. I hated to do it, but the best solution was to eat the $100 for the blower as I could not fixed the connector on the blower. so on to replacing the blower.
There is a small module with two blue wires the move the vent from outside to inside air only, two screws, take it off.
Then there is a plastic cover with a grilled area on the right, 5 screws to take this off and one of the screws is directly against the fire wall, I was using an 8MM socket and combi wrench the whole time. Good luck getting the one on the firewall, I broke the plastic cover to finally get it off. If you have a lot of tools, a short well, 12 point with elbow and extenions and a little bit of luck you can get it off (now try to get it back on!). Everything under here it a bitch to get out, the cover once the screws are removed was a pain, the vent for fresh air or not is underneath and ALWAYS in the way(remember which positon,the fresh air vent is in for when you put it all back together). You just have to play with it until it comes out. I clipped the wires for the old blower, but the gromet that they give moves in and out pretty easy if you need to. Then there are three more screws underneath for the blower assemly, and notice that the blower only fits in one way. Once the screws are removed, it a bitch again to get the blower out past the fresh air vent, but wiggle it around and it will eventually come out.
From here it wasn't to bad, I actually took the glove box completely out as I needed various angles and vision to see what was going on. Replace everything the way it came out (ya right I know, never goes back together quit the same eh?)
The connector I spoke of in the beginning has two screws on it, take those off and the connector falls off, and attached to the back of the connector was the fuse thing (what ever it is anyway). My fuse was good, but I did spend some time cleaning up the melted plastic and polishing the connection point as they were corroded. Turned on the van and WA-LA, blower and vent control working.
Good luck...
