Ohhhhh you've got an 88, not a bonne. I'm not so sure about the part then, we'd need to check GMPD for cross reference.

Heck..even if Stan hadn't fixed the air mix actuator and upgraded the HVAC programer, his daughter wouldn't have been fiddling with it and caused a white curse crash that caused the demise of his SSE

Many thanks to each of you who have provided helpful advice regarding this problem. Bill, it IS a '99 Bonneville SSEI. The car is still at the mechanics and I'm probably going to pick it up this afternoon to get started on the troubleshooting tips above. Thanks again to all.

Marion

I am losing it. Sorry....

He has a '99 SSEi and I knew that, but was thinking of someone else with air issues last week

(Maybe I should go edit out all that crap I typed about the 88 and then refill my prescription of senility medications)

EDIT: "Crap" edited to clean-up post

Ya cut me again, Boosty. Cut me reeeeal deep.
Actually, she was fiddling with the HUD. At a most inopportune time, I might add.

Keep us posted on your troubleshooting, Marion, and if you happen to solve the problem be sure to post your solution here so others can benefit in the future.

Marionh - the programmer connector likes to gum up and plug up; therefor not pass any vacuum. I suspect this is whats happened to you too.

What i did to test is to simply cut those lines. I used 3/8 (pretty sure it was 3/ vacuum hose to connect the mainline (purple - I'm pretty sure) to the various other lines one at a time. Everything switched with vacuum (engine needs to be running) That isolated the problem to the programmer so I removed it and opened it up. It didn't take long to figure out the connector was the problem.

Going 1 line at a time I cut the inside tubing and used the vacuum hose to connect it to the outside tubing. I had to be careful because the tubing on the inside of the programmer wasn't the same color as on the outside. When I was all done I tested with it sitting on the floor and everything worked 100%. I used some small wire ties to act as clamps on the hoses and everything has been fine for 2-3 years now.

Houston, we have AC... and air flow!

The mystery has been solved, thanks to the help of many on the board. The AC problem and the air flow problem were apparently unrelated. The clutch was not pulling in on the AC and so the mechanic said he "spanked it" and it began working and then pulled in every time after that. As to air flow, it was the classic tubing/nipple problem. The mechanic said that 2 of the tubes were actually broken and he used the pictures from posts here to cut and reconnect all of the tubing, eliminating the nipples. Thank you all again for all of your help with this.

Wonderful to hear you have cold and correct flow, again. Another "programmer may need replacing" assumption overcome and fixed for pennies instead of hundreds.

All that was needed was a good spanking to get that monkey off his back.
