1997 Honda Prelude

Nick writes:

Hello Sajeev,

(I really wanted to put the “n” in there.)

I have a ’97 Prelude that will sometimes cycle on and off its air conditioning when it’s unbearable hot outside (June-September here in Phoenix). Air will come out nice and cold, then it will get real warm suddenly for about 30 seconds before getting cold again. It only happens when it’s extremely hot outside and I’ve been driving for awhile. It works fine the majority of the time. What do you think? (Read More…)

Hi Sajeev,

Hope you are doing well. I haven’t seen a lot of activity from you on TTAC lately (but I haven’t been as religious a reader lately either between work and kiddos). I find it interesting what cars default to having their climate control (manual or automatic) on re-circulating versus fresh air. One of the things I like about our Odyssey is that it defaults to fresh air unless the cooling load called for is very heavy (in auto mode, in manual mode it won’t switch).

Engineers added a cold air vent to certain Chevrolets for the 2016 model year to help keep smart phones wirelessly charging in the car from overheating.  The industry-first feature will be available in 2016 Chevrolet Impala, Malibu, Volt and Cruze models equipped with wireless charging and Chevrolet MyLink. The Active Phone Cooling feature works when the car’s heating, ventilation and cooling system is on.

So, the world is coming to an end.

Smartphone users who just can’t handle the thought of their iDroidberrys shutting off because they get a little overheated, GM has a solution for you. The automaker announced a feature in upcoming 2016 Chevrolet Malibus and Impalas that will cool the phone while charging on the wireless mat before it turns itself into a hot brick of glass, plastic and metal.

Finally, engineers at GM got my letter.

I recently acquired a 2007 Honda Civic EX sedan from a neighbor who moved out of the country. I got a really good deal on it and for the most part it’s in good shape. It has 80k miles, 5 speed, and one major flaw. The air conditioning is a little bi-polar; sometimes if blows cold and sometimes not. (Read More…)

Sajeev –

My wife has a 2009 CRV EX-L with a bit over 100,000 miles on it. Its a great car in great condition and seems to have quite a bit of life left in it. Lots of highway miles in a short period of time have been easy on it. But there are two issues:

1) Every time I get in it I smell a very strong musty odor.
2) My wife swears it doesn’t exist. (Read More…)

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…)
