Hi Scotty. We have a 1994 Pontiac Trans Sport with 218,000 miles on it. We can't afford a scanner so it has not been scanned. Yesterday we noticed that the brakes were locked, the ac was not working and neither were the windows. This was sudden as it was fine before that. The fuses are fine. We can't afford a mechanic so we're hoping you can help. Thank you. Arleen.
A generic OBD2 scanner would not work on that vehicle in any event since it is pre-OBD2. However you can access OBD1 blink codes with a paperclip or wire jumper.
You could be looking at any number of problems. A lot can happen to a vehicle in 30 years.
Which brakes locked up? Maybe the parking brake cable is seized? You would need to do some basic electrical troubleshooting to find the problem with the windows. Likewise some basic troubleshooting is needed for the AC. It might be refrigerant has leaked out, or it could be an electrical problem.
Thank you for your help.
