I think this is faster than 60 mph, the vehicle locks and unlocks. every light in the cluster turn on and turn off and there is a message that appears that says: Repair vehicle (air conditioner:confused:) every 3, 4 minute. and one time, the car turn off on highway:suspense:

Re: signal: vehicle repair

Look for any rust where it shouldn't be like inside the truck, on the seat tracks etc. If you find any, most likely the car is a flood car and the electronics are seriously compromised. Car is unrepairable.

Re: signal: vehicle repair

Calling this a 'flood car' is a grand leap considering the limited facts (though in fact it might be a flood car); sporadic electronic 'happenings' can also be something as simple as bad groundings (though finding them might not be so easy). Pretty sure this vehicle is going to be sprouting codes, and if no codes can be retrieved, the ECM may be 'toast'.

Re: signal: vehicle repair

Unexplained rust in unusual place could indicate the car has been in water. I would rule that out first if I were him.

Re: signal: vehicle repair

Every car I've ever owned has had rust over time on unprotected metal parts (including things like a floor shifter, brackets in the dash, some seat parts, etc). This is not necessarily a telltale sign of a flood car. This problem can be explained by a faulty module communicating on the data bus or a number of other possibilities (wiring, connectors/connections, etc). This clearly requires a logical diagnostic approach to determine exactly what is wrong. I will admit though that it 'may' not be easy to track down depending on what it turns out to be.

Re: signal: vehicle repair

Electrical problems that come and go are the biggest troubleshooting challenge in the industry. The usual scenario is for the car to go from shop to shop where either somebody stumbles on the cure or the car becomes undrivable and is scrapped. The best scenario is for the car to go completely dead to where the trouble is hard and fast rather than dodging you.

probleme: fob or sensor?

My car (purchased used) has multiple electronics issues and I'm wondering if it's a fob battery issue or related to other nuisance electrical bugs I've got going on. (Hood ajar warning when it ISN'T ajar; check theft system; check stability system, etc...) I can't lock the car or the alarm goes off thinking there was a theft attempt. and the car turn off on the road :( or the car look like reset the car while running and change the fob name without the other fob inside the car :S i need some help because i dont have the money for a dealer check

Re: probleme: fob or sensor?

Look for mud and rust in strange places; maybe a fish under the back seat. This sounds like a flood car. Multiple unrelated electronic problems indicate a catastrophe in a prior life.

Re: probleme: fob or sensor?

Unless you are an electronics whiz I'd say your problems are about as far from DIY as you can get. This isn't a project. It's more like a career.

--------------------------------------------------

I hope I'm wrong for your sake. I'm assuming you bought this thing for a very low price.
