What would cause the AC on a 1995 Safari to run sometimes then other times just quit?
On my 95 Safari the wiring harness was hanging down and affecting the connection of the low presure switch causing this to happen. Open the hood, look to the left just below the wiring harness. There is a silver evaporator canister with a sensor coming out of it. Run the engine with the air on (watch out where you put your hands around a running engine) move the wiring harness around. If it affect the air conditioning this is your problem. Zip tie the harness to take the weight off of the senor. Good Luck

What would cause the third brake light to not work on a 1995 ford bronco XL both courtesy lights work so there is power at the connection?
You might want to check the wiring for the bulb and the harness for the bulb. My bulb would get so hot it kept melting the plastic harness of the bulb. I now have a small stash of extra bulbs. Answeryou might need to change the light or the cord might have a bad connection some were in the wiring
What are possible causes of taillight malfunction drivers side out during normal operation when brakes are applied drivers side comes on and passenger side goes out?
Most taillight problems stem from grounding issues at the back or from poorly executed attempts to do trailer wiring things. If you have a trailer wiring harness wired in and its factory you can easily unplug this at the back due to factory wiring harness plug-ins and see if that makes a difference. I would also suggest replacing all the bulbs (a relatively inexpensive thing to do) because sometimes one bad bulb can cause the wiring system to act irratically. This is most likely caused by a physical wiring problem and not a computer black box related thing.....but you don't mention what year, model etc so its a bit hard to diagnose as is. Good luck !!!!
What would cause both turn signal indicators and high beam indicator to light up when you turn the headlight switch on?
A short in either the multifunction turn signal switch or a short in the wiring harness going to the switch.
