I set the blower to high weather it is a/c or heat hardly any air comes from any of the vents. The airbag seem to be in the way of my getting to the blower controls. Any suggestions. this is a 93 ssei w/ auto climate control.
#2
traction control and abs lights are on, on the dash the brakes sometimes get mushy and sometimes work so good by stopping the car so fast it is scary. What action should be taken?

#1 First check if the air flow is being directed to the windshield vents although the ECC display shows that it should be coming out the dash vents. This would indicate a disconnected or broken vacuum line usually at the vacuum tank under the hood on the firewall. If the air flow is being directed to the right vents then I suspect you have debris blocking the evap core.

Above is an inside view of the blower module (I guess it's called) from a 97 SSEi. You can see a build up of pine needles in front of the evap core. This is not really enough debris to slow the air flow much.

This filthy mess of a core is from my 90 SSE. This is enough crud to restrict some air and also cause an unpleasant odor.

This is what I found in the blower module cover. It appears to be a rodent nest. This along with the above pictured crud will definately limit air flow. This area and the core can be cleaned by removing the Blower Control Module on the top of the housing and vacuuming out pine needles, nests or other solid stuff. For the core itself, there is a foaming spray that cleans and disinfects the fins. Just make sure that your drain is functioning properly before using cause you need to hose it down after the foam has done it's magic.
#2 Check Wheel Speed Sensor wire connections for all 4 wheels. The connector is after a pigtail about 6" away from the hub, not right at the hub itself. Disconnect and inspect wires and contacts. Clean or scrape if necessary to shine the contacts up and reconnect. I sometimes add dielectric grease to contacts that are subjected to harsh environments such as the underbody.
The mushy pedal feel shouldn't be related to the ABS but more so the "regular" hydraulic system. You might want to check your fluid level and for leaks including the hard lines.
