My 95 Dodge Intrepid speedometer and gas meter is not working along with the lights inside the car and the ac is not getting cold Do i need electrical work or a fuse replace?

The symptoms you describe suggest more than just a "blown" fuse. The first step you need to take is to have a "qualified" [NOT a"shade tree" amateur] automotive electronics technician "troubleshoot" your electrical system in order to first identify the problem[s]. Once all defeciencies have been identified, decisions can be made regarding the proper way to correct the cause[s].
