Thanks for the help yogi. Here is what we found out. It was the Blower Motor Resistor. Which is located behind the Fuse/Relay panel The resister is on the firewall next to the heater core. To get to it you have to remove the the fuse/relay panel by taking off the two nuts that hold it in place. one on each side, the one on the drivers side is undersome plastic and takes an extension to get to. after you remove both nuts you can pull the fuse/relay panel out of the way exposing the resistor. it has two wiring connections going into it. (on our 92 buick) the first one has 1 red wire going into it. the second connection has a purple wire a black wire and a white wire with a black stripe. The resister is held on by the 3 bigger screws. i think like 7 mm. after that it will pull out but it is long so you have to move stuff out of the way just to get it out. after getting the part out its a headache trying to find a new one. the old AC Declo part number wont cross with anything. The only place that could even get one was NAPA and they wanted $170 for a new one and wait a week to get it. we went to the wrecking yard and got one for $5.50. then we found some links where AC Delco has changed their part number
new AC Delco Part #1572530
we were also able to find it as another part number from other stores online as RU-301
here is a link to all of the websites we found and a place to getr a new one for about $100. also there are pictures of what your will be looking for. when installed you will only be able to view just the connectins from the top.
