Help with Rear Heat/AC Fan

[mas1169]

My blower motor for the rear heat/ac recently quit working on my 2000 Venture LS . I made sure the switches were all set appropriately and also checked the 25a fuse. Any ideas where else to look or how costly of a repair this may be? Thanks

First - Welcome to the forum.

Did the motor "just quit" or did it make any noise, not run at high setting or lower settings? Do you smell any "burnt" smells back there?

Probably the best thing to do is get access to the rear motor connector and take some measurements with the controls at various settings. What you need is Power & Ground to the motor. There is also a Blower Motor Resistor Assembly back there (for different speeds).

Inspect all the connections and see what you find. It could be that something has come loose. Let us know what you find.

When my 99 Venture rear fan motor quit working, I pulled part of the left rear interior cover (the black compressor panel insert only), reached down and played around with the plug. I noticed that when I wedged it forward (toward the cargo area), the fan worked, and when I let it go, it stopped. I didn't totally disassemble the cover and unit because I was getting ready to leave for a summer driving vacation, so I really couldn't see what was going on down there but it was obviously an electrical connector problem. As a quick fix, I cut about a 1/2 inch length of 1 inch pvc pipe and wedged it between the fan motor housing and the electrical connector and held it in place with a piece of duct tape. Since it worked fine that way for the two years until I got rid of the van, I never did anything further. The whole "fix" from start to finish was less than 20 minutes and cost nothing (and the kids were really happy they didn't have to drive all the way to Florida without rear AC). Maybe you'll get lucky too.

Sold it with the "PVC Pipe & Duct Tape" option?

Or did you trade it in?

Either way, it makes me laugh thinking of when someone gets a look in there to find your handy work! Thanks for the story.

The story actually gets better. Because it had over 140,000 miles on it (and the dealer would have given me virtually nothing), I just gave it to an old biker friend who needed a car. Within a month, he ran it out of gas. Still living in 1970, he poured some gas down the intake to "prime it" , closed the hood, and then proceeded to try to start it with the gas pedal depressed. (I explained electric fuel pumps and fuel injection to him many times, but he refuses to understand) To make a long story short, the air filter housing burst into flames and one of the first things to melt was the front hood release cable preventing him from opening the hood. He literally (and successfully) punched his way through the left front headlamp assembly to try to get to the fire, but having also spilled gas on himself during the "priming" process, his clothes burst into flames as well. When the fire truck arrived, he was down to his underwear rolling in the snow in 20 degree weather, all of which occurred in the inner city with an audience. Now if that isn't funny enough, about 2 years before, I had sold him my bike which (as I explained to him) was in mint condition but would need a new battery soon. On this particular bike, the battery was under the seat. A week after I sold it to him, he replaced the battery with an oversized (taller) unit he had laying around. Of course, he saw no need to reinstall the "spare parts", namely the rubber terminal insulators and the molded rubber sheet which covered the entire top of the battery. As he rode home from work that night, his 240 pound butt pressed the metal bottom of the seat down where it made contact with the battery terminals. Not knowing what was happening, he just continued to ride on thinking to himself, "Gee, this bike seat gets really hot ... Anthony never mentioned anything about that." Eventually it became unbearable and when he finally pulled over, the bike was just bursting into flames. Unlike the Venture episode, he wasn't ignited or injured in that little mishap, but the bike was destroyed. I couldn't make up stuff like this if I tried.
