2004 Saab 93 Linear Heating and CD issues

Issue 1:

My heat had given our in my car in my car. I took it to the mechanic got a quote. They said that the heating coil was wearing out. Now, however, it is back. I was wondering if the heat gave out because of the extreme cold weather here in Chicago. Should I continue to get the heat fixed or consider it a fluke that it started working again? Is the heating coil wearing out a likely story?

Issue 2:

I put a CD in the player and is stuck now. I cannot get it out. Is there any technique I can use to get it out rather than taking it to the dealer or mechanic? Please help!!! I am tired listen to this garbage on the radio :wink:
