95 dodge Intrepid your check engine light was on now its not your turn signal stop working you replace flasher turn signal on switch and they worked a few time and stoped again Fuses are ok you need?
If the check engine light is on you need to borrow, rent or buy a code scanner from your local auto parts retailer, and use it to find out what's wrong. Do that first, then worry about the other stuff since it might just solve your problem.
I had to replace the engine in my 2002 Intrepid and it cost me a good $3,500. They have to match the year and vin number up with a compatible engine and the mechanic will need to tear the whole front end apart to lift the engine in/out. I can tell you there are very few engines left when I was searching for one a month ago.
