Sounds like you have a dirty Mass air flow sensor...it is located mass air flow tube.( main ) air intake..try some cleaner made for it..or go to a auto parts site like auto zone and see what years and models it fits many have the same that interchange...being a 1990 you should be able to find one at your local salvage yard for a reasonable price,,new ones can get pricy...it is an easy off and on job..good luck..

Sorry to say, If you had the work done at a shop. shops just don't give your new, remanned,or used motor or transmission the best shot at living a long or extended life. Unless new. But ts is still marginal.

Look in the fuse box in the engine compartment.

Look up into the housing over the plate. You should see two glass lenses, and screws holding them in. Unscrew screws, remove bulbs, clean socket with contact cleaner and refit bulbs or new bulbs after cleaning glass lense and reflectors on the inside surfaces as dust and water will have entered and clogged it up over time.

Is it the brake light or the tail light? When you park and get out of the vehicle and see the rear light on put the indicator/slasher stalk in the central position. If it is in the left or right turn position it acts as a parking light on some cars so that a collision does not occur. It is a safety feature. If you put the flasher/indicator stalk in the central position and the light still stays on then you have an issue. Try it

either VG30E 3.0 litre 153 HP V6 or KA24E 2.4 litre 140 HP 4cyl

Tristin, none of the options are good, every thing you said points to head gasket ,exhaust gasses are getting in to coolant side of motor via head gasket, at the same it builds pressure in coolant side over heating motor , see what tail pipe looks like water coming out ? or a steam build up when driving , a pluged thermastate ,can start over heating problems that may lead to further damage. sorry to be the bearer of not to good news . weigh all your options and do your research ,before making a decision.. really good luck. hope this helped .

It sounds like there is an electrical fault with the Remote locking circuit. When you lock the vehicle, without seeing the schematic electrical drawing, there is a relay that will operate to lock the doors. This applies power to the small motors installed within the doors, that operate the locks open/close (Lock/Unlock). Generally there is an electrical componet that by passes the relay once the doors are locked so it doesnt burn out, e.g Capacior. With that in mind, if this component is shorting out, power will be applied and/ or released from the holding circuit which in turn, will operate the vehicles locking mechanism. Best way forward 1. If you have a Gregorys manual, available from Super Cheap Auto for under $50, it will have the Electrical circuit drawing for the Door locks, if it's standard fit to the path finder. You will be able then, with the use of a Multi meter, to check out where power is getting to or not (12V dc). 2. If not give the Auto electrician $50 to fix. As the Nissian is 24 years old, I would be looking for a electrical component failure. I hope this helps you out mate, Stevie C.

Look up or google the codes & diagnose them

Check your fuse panel. The relay should be protected by an appropriately-named fuse. Good luck.
