Hey everybody! I've been gone a few weeks. Between the flu, my new job, and the vagaries of my standard issue life, I've just been super busy.
Unfortunately, a new electrical bug (Is my 98' LSC the super rare "Built by Jaguar in Coventry Edition"?????) is the impetus for my timely return. Here's what we know:
#1. I was doing the "wiggle fix" for months until about three weeks ago when I finally got down there and did a more permanent (I thought at the time) repair of cleaning and crimping the contacts. After that, All was well till now.
#2. Three days ago the blower just cut out. I was driving around, stopped at The New Jersey Home for Cranky Middle - Aged Women, and when I came back out and restarted the car, the blower motor refused to work. I was a little annoyed, but not worried, thinking it was the same old thing. I was wrong.
#3. The refurbished electrical connection I did last time between the little box thingy mounted under the dash (I have dubbed this little box thingy the "Blower Motor Speed Control", or BMSC, even though Im pretty sure thats NOT what it's called, or what it does. It shall be hereforth referred to as such.) which is in between the CC head unit and the Blower Motor itself, is still tight and intact. Also, obviously. the "Wiggle Fix" did not work.
#4. The CC self-diagnostic that is accessed by pressing Off and floor simutaneously, then Automatic within 2 seconds will not work.
#5. The blower motor will spin when I put a 9 Volt battery directly on its contacts. The Motor is not the problem.
#6. I have 11.6 volts at the end of the Blower Motor electrical connection (the black and orange wires that connect directly to the motor itself). This means that I am at least getting voltage after the suspect BMSC, although the illustrious personages of Steve and Driller tell me that this doesn't mean I have current as well, I am not actually smart enough to discern this distinction, and therefore have chosen to ignore it.
#7. The BMSC fell apart to reveal moderate corrosion which is illustrated in a picture that I sent to Driller from my cell phone. I am also not smart enough to know how to post said picture here, so hopefully JP can do it when he reads this.
#8. I reconnected everything, although I did leave the glovebox and lower dash trim dissassembled, cleaned the BMSC circuit board with electrical contact cleaner, and left it sitting on my passenger side floor. (It is still electrically in line with the blower and CC head unit{Which is fully operational BTW} and just hanging down by the wires onto the floor)
#9. Driller, who so graciously gave me part of his Saturday afternoon by phone, and I concluded from this picture that the BMSC was DOA and therefore the culprit in this issue. I decided that I must then search out a new BMSC, and began to make calls. No luck with that so far. You might be thinking that this issue seems resolved, but wait...... there's more!
#10. On my way home from the previously mentioned new job, (which SUCKS, in case you were wondering) the blower motor magically began to work! I had left my CC set to Auto 78*, where it always is, in the hopes that this very thing might happen. I didn't hit a bump or pothole that might have momentarily reconnected a short, as a matter of fact, I was stopped at a light the first time it came on. It came on 4 or 5 times throughtout the ride home, staying on for the longest of those times for maybe 15 seconds, and the shortest maybe 3. The thing is, that circuit board on the BMSC is totally effed up. (Hopefully Driller has posted that picture so you can see for yourself.) Even though I did clean it and attempt to get some of the corrosion off, I didn't think that solid-state electronics could come back from this kind of thing. I'm under the impression that once they are in this state of disrepair, there's no coming back. Maybe I'm wrong? So here we are, now IDK if this BMSC is really the problem or if it is something previously unconsidered. All I know is that even though my baby is running great, having no blower motor is a serious issue in my book, and I would love some insight on what could be wrong. Also on who has a new BMSC if this is confirmed as the problem. I don't want to order a new one from Lincoln, (if it's even available) and then find out it's not the problem cuz they most likely will not allow the return of a special order electrical item. Happy Thinking!!!!!
