year/make/model???? This light may be on to inform you of an operating system problem and will not go out until the codes are checked/erased. Depending on make and model, it may be a service light letting you know the transmission is due for a service and will be turned out by your repair facility. Do not let this light go unattended as it could lead to costly repairs
get the code, the 02's most likely have nothing to do with this problem. The 02's purpose is to tell the PCM you have a fueling issue or misfire issue. The fact that the light is flashing tells me you have a misfire going on and they are doing thier job. Why pay 100 bucks for a part that wont fix this when you can pay someone 100 buck to tell you what your problem is.
What you have to do is go to a service shop and get the codes from the transfer case control module.This will help you find out what is causing the shifting problem.When the technician gets the codes there is a trouble chart that is followed to find the problem.Weather it be a sensor,wiring,switch,or wiring problem.This would be the best way to fix the vehicle other wise you are just throwing parts at it and this can be very costly.Unless you know someone with a scanner and a service manual this would help.Hope this helps.Let me know what you find out.Good luck.
ok ac system has a pressure switch that stops the compressor when freon is too low. they actually say it is ok for mobile a/c systems to lose a half pound a year. most a/c systems run on under 2 pounds of freon. so after 3 or 4 years some systems will just quit working. you are at 8 to 9 years so i would recommend you find an independant shop that will top off your a/c and see if it works again. this should not cost more that 50 to 75 bucks. If you were here that is what i would charge. I am in columbus ohio just to let you know. hope this helps and thanks for using fixya
nissan's have lighting problems on clusters and ac controllers. remove cluster and take it apart, replace bulbs, you can get them from radio shack. its an diy fix, will take about 1 and a half hours and will cost about 10 bucks at most!
fix the vacum leak unfortunatly there are a pile of vacum hoses in the eng compartment so giving you an answer as to whats leaking is impossable. That being said the ac system is a balenced system too much pressure or to little and the ac clutch on the motor wont engage to circulate the freon or coolent. If the clutch clicks on and off or dosent pick at all usually its a coolent presure problem to low to high or a blockage any ac service station will be able to hook it up and give you an answer in 30 min or less shouldent cost more than 75 bucks to at the very least fix the vacume leak and get a bead on the ac issue good luck
The service engine soon light comes on for many reasons..it could be as simple as CO2 sensor, or it may just be one of the lights that just stays on, ask your local GM garagre to reset the code for you..maybe cost you a couple bucks.
Dealer labor will be about 88-105 bucks an hr plus a diagnosis charge prob about 40 to 65 bucks, at least it is at my Chevy dealership, you can get a hand held code reader at auto zone which you plug into the cars computer and it will tell you what caused the light to come on, I think those are 30 or 40 bucks
I had the same problem. After taking the MAF sensor off and cleaning it, it was still there... I ended up changing the throttle position sensor and all was well. It cost about 23 bucks..You can try this first.
