#396 of 444 rprez8 car shakes when a/c system turned on

Your problem sounds like a problem with the IAC ( idle air control) valve,,and or the vacuum passages that this solenoid switch controls. This device has a pintle, a pintle looks like a little piston with a point on one end, in response to engine load, the pintle moves back and forth and allows bleed air to bypass the closed throttle plate,this action increases the engine rpm. The vacuum passage that goes from the front of the throttle plate, to the iac passage, and then to the back of the throttle plate may be dirty,also the iac valve may be malfunctioning, be sure to properly diagnose the iac before replacing it as it is an expensive item. The way the circuit works for the a/c is as follows: You turn the a/c on, the TPS (throttle position sensor) tells the ECM that the throttle is closed, the A/C Cycling Switch tells the ECM that that there is increased pressure in the a/c system. The ECM sends a voltage signal to the IAC to operate and the idle increases,,as you drive the ECM receives a signal from the TPS, and the A/C Cycling Switch, and the ECM stops the signal to the IAC, since the car is not at idle and while the car is moving increased idle is not necessary.

I would agree that it may be the IAC valve. I had thought of that, but dismissed it.
Since that part is expensive you may want to try using a air intake spray cleaner first to see if it helps.
Disconnect the hose that comes from the air cleaner to the intake at the intake (engine) end, There is a plate in there ...look inside you will see it...spray in there with the cleaner.
I did this once on a Toyota and it was a big help.
I have never heard of laser plugs....did you mean irradium ?
Just courious...how many miles on your Aerio ?

Ok, I got two unrelated problems with my SX. I love the car and I bought it used from a non-suzuki dealer. My father took care of alot of the dirty work getting the car and needless to say I am not gifted in the area of car maintenance. Recently my AC started acting up, it works but the fans don't work. I can only get cool air when the vehicle is in motion. Also, a passenger of mine slid out of the car and accidently popped out my passenger side Side Skirt piece. I tried popping it back it but it seems too stiff. I don't want to take it to a shop just so they can charge me for something I can do myself. If any one can help me with either of my problems I would greatly appreciate it!

Check the fuse for the a/c blower motor.

I am going to look at a 2004 Aerio Wagon automatic, with 34,500 miles on it....any ideas or thoughts. I have had a Datsun and Nissan that were well maintained would last for 200,000+.....I have read good and bad on here.... looking for advice and back up ideas in general. I maintain my vehicles for I cannot be without a car nor broken down....only happen a couple of times in my life and want to keep it that way.

My 2003 wagon seems to eat batteries every three years (but that's because I stop at a 7-11 almost every morning about 10 minutes away from my house; I help another commuter get to work). Closing on the the third-year mark, the car is hard to start after turning off the engine on short runs.
If the drive is five miles and/or 15+ minutes in length, my generator charges the battery enough to maintain normal starting.

First....is your alternator belt tight ?
Second....is the alternator output per specs.
Hope this helps.
A lot of auto supply stores will check the alternator output for free or you can buy a cheap tester for around $6.00

If you haven't checked your battery in 3 years, the most likely culprit is oxidation of the battery connections. Many times, just removing and cleaning the connections can restore full function. Of course, most less expensive batteries are not warranted beyond 36 months, and the guarantee is virtually worthless in the 3rd year anyway, so they don't worry much about failures in that 3rd year. Running with raised resistance in the system can also burn out both the battery and the alternator over time. I use those stupid little red and green pads under my battery terminals, and they seem to work.

During my last oil change, I asked my local shop to check the battery; the shop replaced the battery posts and connections, which were corroded. It helped somewhat. I'll see about checking the other conditions later this week. Thank you!

Looks like I read the wrong maintenance interval in my manual. My favorite maintenance shop looked at my ATF, and it was black. 89,32x miles on the clock. The shop recommended that I have a specialist change the fluid; they didn't want to touch it.
I looked up the situations that could come with black ATF sloshing within my system, and things simply don't look that good even if I choose a professional flush. Fortunately, I am a zealous saver and can take the potential hit (it will be painful, regardless).
The next time I get an offer for a fluid change at 30k or 60k, I won't hesitate taking it.
