What is my issue?

[Motorhead350]

When I turn on my A/C it simply blows air (usually warm) until the car gets some air flow going or I turn it down to 68. I think my a/c needs to be recharged or something. Also during the fall it's really cold air until I turn it up to 90 then it can go back to 75, but it will still blow cold air every once in a while. Are these problems related? The A/C didn't occur at all in the past five years until last week.

If it blows cold when turned to 68 degrees you shouldn't need a recharge. As the outside temperature changes and gets lower you have to turn down the set temperature inorder to get cold air inside car.
As far as the second symptom if you have to turn it to 90 degrees first before getting any heat the temperature blend door may be sticking. Try running the self test and let system run thru it's own check up as directed below:


The service manual shows how to run a self test check on the EATC.

Press the OFF & FLOOR buttons at the same time and release. Within TWO SECONDS press the AUTOMATIC button and release.

The display will change to the self test mode which basically is a dash symbol ( - ) that chases itself in a square rotation pattern. Any trouble codes will then appear.

To exit the self test mode just press the BLUE (cooler) button.

If you get any codes post them here and I'll look them up in the service manual for you.
