The air is dual air control but it is manual dual air and the air and cruise both quit working at the same time it started out the air would lose power for a minute or so then it would come back on and work for a while with no problems and then it got worse and would only work on high and now it will not come on at all and at the same time the cruise quit working. What would cause this to happen and about how much would it cost me to fix and or how could I fix it myself ?
You have two on related problems , just a coincidence they stoped at the same time . The cable inside the cruise control module is probably broken , this cable is connected to the cable that opens the throttle . I'll post a video to show you what i'm talking about !
No Cruise Control Buick LeSabre You can buy this part for $10 to $20 buck ! Change it out in 10 min.
Now your other problem is the Blower motor isn't blowing air out of the vents ? The way you describe it working then on high only an now not at all this could be the motor . Unless the motor was bad enough to take out the blower motor resistor an the high speed relay as well.
Testing would need to be done to find the problem !

I found the problem. It was the crank position sensor. There was also a cracked vacuum hose connecting to the diaphragm on the fuel rail. Replaced both and my 92 Buick no longer dies. For the guy who's Buick was dying when using the turn signals - replace the crank position sensor. One of my symptoms of my Buick dying was when I used my turn signals. Use of turn signals places a varying load on the electrical system which messes up the crank posistion sensor if it is going bad.
