Cold air from driver's side?

[Soonerfan]

I'm new to the forum here, so I thought I'd throw out a couple of questions.
I have a '96 Seville SLS. When I turn on the heater or vent, a different (cooler)
temperature of air comes out the drivers side vent and the left side of the center vent. What could this be?

Also, I have a "Security Ststem Problem-car may not restart" message. I know it's the cylinder, but is there any way to bypass the cylinder, or do I HAVE to replace the cylinder?

Thanks for your help!

Your heat problem-new heater core. Search the forums on it, you'll find dozens of threads dedicated to the heat problem.

I have a 97 Park Avenue that does the same thing. I've seen it blow ICE cold out the drivers side and HOT out the pass side at the same time. I haven't had a chance yet to look at it.

Does this have the PassKey3 system (PK3 on the key blank). If so you can't bypass the PassKey module so if it is bad you'll have to replace it. You may be able to reprogram it.

Hello, in order to bypass that system all you have to do is take a ohmn meter and check the resistance of the chip in your key, find it then go to radio shack and by some reistors and start combinding them untill you have the same resistance value.
Then under your dash find the elec. connector for the ign. cylinder, cut it on the side off the cylinder(this way you keep the factory harness in good shape) solder in your resistor and you are set to go.
Another option is to buy a key of the same resistance and use it's chip. They are costly and for 2.00 dollors you can get a handful of resistors.
I have done this to numerize vehicles in the garage and broke down along side the road.

Sooner, Different temperatures from different zones generally indicate a blend or flow door actuator hangup. Assuming the car heats up to operating temperature and that the floor vents blow warm air when requested by your setting the MODE, try going through several different modes and blower speeds. If that doesn't cure the temperature balance, then you're into Factory Service Manual territory to figure out which blend door is hanging up.

Thats a nice first post.
All You Have To Do Is............

Here to help or to brag ?

Gotta remember kid, the reason that the question is posted, is cause there aint a clue as to what your talkin about.
Chip for what ????
And BTW... where is the ignition cylinder ? Does anything need to be removed to get to it ?? What does it look like ?

Slow and easy man. Just cause you've done it many times, and it may be your field of expertise, doesnt mean everyone else has a clue as to what your sayin.

Laymans terms are always nice.

And wondering as well.........??? Are you always so quick to a diagnosis even when not seeing and or checking out a vehicle ? If this person was do to what you said (to the letter) and still had the same problem. Or even more problems for that matter ! Would you compensate such individual for your misdiagnose ???

Suggestions and insight to ones experience is what this site is about.
But I myself have always had a problem with advice that leans towards a statement of fact.
There is a huge difference between opinion/helpful suggestions, and true diagnosis/statements of fact, of any individuals concerns.

The only reason your commenting on his post is because there is a 1 by his name. His first post i've seen plenty of other people give advice like this and you have not replyed. I've seen people like you on all to many forums. If the user did take his advice and did do it then i'm sure he would ask questions to be more specific. Stop picking on the newbs.

Are you here to help or to pick on people ?

If you are in the heat mode, it may be a clogged heater core. Flush it. If in the A/C mode, probably a bit low on refrigerant. Top it off.

Or as Sub said, a blend door. Sometimes it will help if you run the temp all the way up to 90 and then back down. If the door is sticking, that will exercise it and bring them back in sync.

Im here to help.

And just because I didnt start the thread, does that mean that Im not allowed to ask for more specifics as well ?
Does that mean Im not entitled to learn as well ?

"....where is the ignition cylinder ? Does anything need to be removed to get to it ?? What does it look like ?"

I also asked him to be slow and easy.

As you should know your self....being one whom frequents many sites as these, as you have stated, not all members are tech savvy and know what they are doing. Which is the reason why these sites prosper.
Was just tryin to let kid know that "Laymans terms are always nice".

Ive also been in a few forums. I may not have as much time as you to be in as many as you may be in. But the few Ive been in also have all the same kind of people. You have the so called internet heroes that think they impress by telling others exactly what there problem is. No detail or anything. No care for the other member. Just flap off "telling" someone they know what the problem is for sure. And giving info that is only useful for someone that would already know what they are talking about.

Its a help forum. And people come here for help they can understand. And people come here to learn to help themselves and then maybe hopefully others. If we were all able to understand the manuals then these sites would be obsolete.

Was just tryin to let a new member know that para phrasing a manual is not necessarily helping.
And if hes been in as many help forums as you have, then he should also know that.
But then again. You weren't aware of that either.
So am guessing that most of the forums you go to are ones where individuals want to show off first then help later.
(oh ya ! Ive also been in/seen those ones too LOL)

Sub and Ranger have given the best advice. Check this, try that, then go from there. As advice should be given.
Like I said, I "have always had a problem with advice that leans towards a statement of fact."
And to tell some one to start taking things apart without knowing what the actual problem is..............Like Ive said.....I have a problem with that.

BTW...seeing as you thought you knew my reason for commenting on this post......I really, really, really have to ask .........

What was your actual reason for commenting on this post ? It certainally wasnt to help out the original poster. You gave no advice whatsover. No queries as to any other advice given either ??? What did you add and or ask ????
All you did here was bitch at me. You said you've seen people like me on many forums. Take a look in the mirror. You just put your self well below the level that you attempted to drop me to.

[wvkid]

I have over 25 years in the GM field, with Cad. being our first franshise name I am sorry if I affended you, but most people that respond to these type of forums will follow up and ask quistions, of the responder. I would garuntee that this would fix that vehicle and any other 1 that had that problem. Reread the quistion, he wanted to eliminate the chip because of cost. So if his vehicle wouldn't start afterwards that would be a owner induced problem, wouldn't it.
As he has not wanted any more info on that subject and the only responce started a war.
I will not post anymore replies after this one, and you should tone down your replies.

[Murphyg]

Will do my best.
But dont stop posting just cause of one belligerent me.

[rwjiudice]

I had the same problem with cooler air on the driver's side, hot air on the passenger side.

So I posted here and Ranger said it probably was a heater core that needed flushing. I thought "how stupid is that?" "The core is either plugged i: no or low heat, or ok".

Stupid me!!!! I flushed the core.... and what do you know? HEAT!!!!!!

Be a believer in the folks on this forum...... they know what they're talking about. Good luck (and let us know how it works out)
