My blower fan will run with the key out, but will turn of with the fan switch. I changed the A/C relay under the dash and it seem to fix the problem.

Have your charging system checked. I had a similar problem with a chrysler van - the lights would brighten and then dim periodically. it turned out to be the battery.

SOURCE: lights go dim
If you're running the car under a heavy load, lights will dim briefly (ie. you turn the ac on full)
With the engine running, the leads on the battery should read 13-14V
