Sajeev -
My wife drives a 1998 328i that we bought new for her- it currently has 64,300 miles on it. She drives it more or less daily (just not very far) so we couldn ’t just get rid of it; it would have to be replaced. I call this car ”The Immaculata” as it lives in covered parking and is often mistaken by her un-car-savvy girlfriends as almost new.
Unfortunately that isn’t the case. It got a new hood and fender after ”an incident”, and it’s ticked off the list of usual E36 demands. New shocks, radiator, etc. However it’s gotten everything it wanted including regular oil changes and radiator and brake flushes and a transmission flush as well.
Now it’s advanced down the list to having the HVAC mix door slam open when the heat comes on. My Independent macanic say $1,500 to fix that but it annoys the wife.
Thought about replacing the car, but I’m kind of stuck. She’s used to her heated seats and the easy power of the BMW. The suggestion of a new Mini was sneered at. However obviously this car, even in great condition as it is won’t be worth enough to make the trade for a new 3 – and she won’t eventry driving my 2011 anyhow.
So… should I bite the bullet and fix the noise she’s complaining about, bite the shotgun shell and dump it while it’s as valuable as it will ever get and buy a new car she doesn’t want, or tell her she’s crazy and that I don’t hear the noise? (Read More…)
Geek alert! This one is tech-heavy!

Sajeev,
Not a question, but it’s good to know that as long as there are cars there are people who will come up with hacks, no matter how complicated things get.
I have an 1992 Cadillac Seville and the blower motor fan disintegrated and jammed up the blower motor, which in turn shorted out the blower resistor. The squirrel cage disintegrated. I checked inside the blower housing to see if there was anything loose, but I could find nothing except pieces of the fan. All of this stuff was OE, no one has been in there since the car came from the factory. I’m sure someone at GM thought that saving a nickel on plastic was a good idea. Well, I bought a new motor/fan assembly and installed it. Wasn’t too bad, about $40. When I tried it, it was a no-go. Next thing I do is check the fuse (30 amp) it was fine. Then I checked the blower motor controller. It was blown. Crap! Apparently when the fan blew up, it jammed the motor, which then took out the motor controller. I’m thinking to myself:
“Nice engineering. The components on this circuit blow before the fuse does. WTF is the fuse for?” (Read More…)

Sajeev,
I recently picked up a 1969 Cadillac Sedan Deville. It was one of those once-in-a-lifetime deals you only hear about, like my uncles cousins sister is selling her deceased husbands garage queen for pennies on the dollar deal.
My problem is, the Automatic Climate Control (a $550 option!) does not work. The only settings that trigger any response are FOG and ICE. Even then, I can only hear the blower motor and just barely feel air from the floor vents. Where to begin the troubleshooting?
Thanks,
Kenzter

Remember how the California Air Resources Board was contemplating banning black cars because air conditioning uses so much C02 (or not)? Well, the madness is over, as The Detroit News reports that California’s proposed “Cool Car” rules are dead. What killed them (besides common sense and the laws of diminishing returns)? Law enforcement, for one, which warned that (Read More…)
