No, you have a vacuum problem. The HVAC defaults to defrost/floor without vacuum. Check for a hissing sound at the firewall. Usually the vacuum line between the throttle body and the vacuum tank on the firewall is bad or disconnected. May have become jarred when replacing the blower.

I have a 92 SSE and the blower moter will not shut off. I have ripped most of dash apart and can not find the relay or module. It is a full loaded car with climat control. The controls will not shut fan off. I think the fan is running at half throttle, not able to adjust either way. Any of you experts have a solution?
Thanks,

Is it on even when you shut the car off?

Yes, I have to unplug the fan under hood to shut it off. I have tried unplugging the controls and still runs. I run the diagnostics check (I found on this forum) and I get error 138 and 152.

The problem with your fan is also the blower control module. Unfortunately you need a new one too.

Why couldn't it just be a fuse? Oh well off to the parts store I go.

Thank you,

Follow-up to the A/C only blowing through defroster ducts: the culprit was in fact the electronic climate control unit which is responsible for vacuum application to the appropriate servos for blending/directing of air. Pontiac dealer replaced it (I did not feel like laying upside down on my back for a prolonged period of time to try to replace - sometimes you gotta pay the the Service Dept.) However, there is a bit of good news, the part listed over $600.00 from the Service Dept., but the dealership cooperatively dropped the price to wholesale when presented with a parts quote from www.GMpartsdirect.com for the part - saved around $200.00.

Too bad, but I doubt I'll EVER buy another GM product with either dual zone or automatic climate control. Every car I've had that ever had one of these features was problematic. Seems like another feature on which GM doesn't do their homework to make it right, are overly cheap about construction, or intentionally want return service work. A disappointment.

Thanks again to everyone who commented.

It'* too bad you feel that way. The newer LeSabre has electrical controls on the motors--no vacuum. The vacuum problem with your older one was like our 98 LeSabre. A connector in the corner of the programmer has nipples that collapse and block the vacuum. I fixed mine from the following repair--it cost "free" for the 1/8 inch gas line to reconnect the 5 vacuum lines inside and outside the programmer, NAPA Donated the 6 inches:

My service manager had told me about the nipples collapsing but he suggested a junkyard-programmer $100. Removal and replacement of programmer to work on it is about 30 minute project after you know how dash comes apart.

Dealers also don't tell you the key chip reader wires breaking can be replaced with a resistor at the base of the steering column instead of a $200 repair and new keys.

And they don't tell you about the electronic control for heater blower fan speeds on the housing outside that you can replace yourself. I found all these things on forums like this one.

Thanks guys.
