Okay, so here's the deal. This morning at 3:00 AM. That's right, I work insane hours. I go outside and it's probably somewhere around 5 degrees fahrenheit. What a fine time to find out that the day before I left the headlights on and ran the battery down. So I pulled my mini-van around to give the 245 a jump-start and rounded up the cables. I then hooked everything up and waited about 10 minutes in the van (which was already warm). After a few tries I finally got the 245 to start. I then disconnected the cables and put them in the 3rd seat compartmentand moved the mini-van back to it's parking place and shut it off. Then I hop into the 245 and realize that the heater blower motor is only on "2". Now to give you a little background info about this blower motor, when it's cold it will squeal for a second and then will immediately silence itself and continue to run fine. Now, I'm not new to the blower motor scene on these cars as I've changed a couple out on my last 245. So I'm hip to the fact that this motor is on its way out and I'm trying (and hoping) to nurse it along until spring so I can change it in anti tundra-like weather. It's nice to be able to feel your fingertips (ahh...the simple things in life!). Anyhow, without giving it a second thought I turned the blower motor from "2" to "4" with the knob and the motor let out that familiar squeal and apparently caused such a large amp draw on the electrical system that the car actually died. Well, back to pulling the mini-van back into place and hooking up the jump starter cables again. After I got it started the second time, I waited to be going down the road before I turned the blower motor on. It worked fine after that. I've worked on cars for the past 30 years and I've never seen a blower motor cause this. Has anyone else had a similar experience? Just thought i'd pass this one along.
