Good Luck!

Also, let us know if your temperature display blinks when you turn the car on.

Where exactly is this vacuum reservoir located? I have looked to the left of the master cylinder and I do not see what you all are describing............is it different on a 96 model??
I have the standard a/c controls, but I have had a problem with the air switching to the defrost under acceleration for a long time now............

The vacuum reservoir is usually over on the passenger'* side, mounted on the firewall or the evaporator core housing, somewhere in the area of the right (passenger'* side) hood hinge. Its location varies from one model to another. It'* a sperical, black plastic thing maybe 4" or 5" in diameter.

If air switches to the defrost under acceleration, you're losing intake manifold vacuum. The reservoir is supposed to compensate for that short-term, but if yours keeps running out, look for a vacuum leak somewhere, or excess backpressure from a partially clogged catalytic convertor. (If your top-end speed is down, or the transmission hunts in and out of lockup at highway speeds, check the convertor.)

Thanks Jaime for the info, i'll try that out this weekend.

When i turn on the car, the display doesn't blink. Everything appears to be normal.

acg_ssei, i looked all around to see if anything was dissconnected the other day and couldn't find anything but i'll take a closer look this weekend.

I have a 92 ssei and I have just about the same problem, but mine is blowing some air from the vents. I have changed the blower and it didn't help.any ideas?
I just found your site the other day and I think it'* great, I've already used info to diagnose a low freon problem which will be fixed Monday. Thanks

If the problem is a general lack of volume, you're getting some air from the center vents but not a lot, you might need to clean out the heater cores and evaporator cores. There'* a procedure for that in the TechInfo area: http://www.bonnevilleclub.com/techinfo/?article=62
