remote starter don't work

my remote starter on my 300m quit working. anyone have any suggestions on how to fix?

Fuses? Loose wires? You didn't give any details, and details help to determine what is wrong. Check your manufacturer's website. They may have a helpful hints/troubleshooting page. Also, if someone else installed it you may want to check with them as well. Other than that, start going thru the entire installation process step-by-step to see what may be wrong.

i just had the a.c. unit replaced so they might have loosened a wire or unhooked it all together and forgot to hook it back up. does it have a seperate fuse just for the starter?
