On my 87 when I start the car the abs light comes on and goes off. When I back out of the carport and apply the brakes I can feel the pedal go down slightly and the abs light comes on. It remains on until the car is cut off.This happens every time. Also my cruise doesn't work. I was told that it is tied in with the abs system. I have been told that it is a speed sensor. Then I was told that it needed the brakes bled. It had new brakes on it when I purchased it. I do n ot want to spend money guessing.
Now the ac. It has a new compressor. It gets cold. You can feel it blowing extremely hard and then it gets weaker. I also feel cold air on my feet. The car only has 87000 miles and has never been wrecked or repainted. With a new GM glass top and the ac blowing weaker it gets hot .I have not noticed it getting stronger until you cut the car off and then restart it. ANY ADVICE WOULD BE GREATLY APPRECIATED.

I don't know what's going on with your ABS, but it sounds like you have a bad connection to your A/C fan.

The cruise is independent from the ABS.One of the wheel sensors may be fulty or not connected.

The common link between the A/c and cruise is they both rely on vac to work.
Have you checked the vac connection from plenum to firewall ?
Hoses to the vac ball under drv side headlight?
No/ low vac means the cruise won't pull in and the HVAC vents under the dash say in the default position.
