05 Envoy Problems

[sloticus]

Hello,

I have a 2005 Envoy that recently had a check engine light come on. I took it to the dealer and they told me that my fan computer was bad and that it would be around $800 to fix. They mentioned that an aftermarket part was available but that it often did not work. I noticed that my cruise control does not work now that I got my truck back. I also have an issue of the A/C not working at idle, but blows cold while underway. I don't have the cash to shell out for the dealer repair, so here i am. Thanks in advance.
