My husband took our 1999 Land Rover Discovery in for an oil change yesterday morning and later he noticed that only the four way flashers would come on when he tried to put the left or right blinkers on. Could it be because of the oil change? Do they have to touch anything near the computer or wiring to do the oil change? Can someone who knows these vehicles help me please? He also drove through a deep puddle yesterday that caused the Rover to just cut off and it wouldn't start for almost an hour. It is running and driving just fine and everything else on it is working great. Help Please!!

They probably forgot to put the plug back in for your blinker fluid. I would call them and ask if they still have it there.

Sounds like an issue with the wiring - a short in the turn signal cables or something. I don't think an oil change would have anything to do with this, there's nothing electrical involved during the process.Driving through deep water isn't a good idea - if you get water in the air intake, you could ruin the engine. My friend had a Ford Escort and had to replace the whole engine when he went through a puddle at the mall that was too deep.

i sell land rovers changing the oil has nothing to do with the wireng, there is a fault in the system espically if you went through water there is a fault in the system take it to a land rover dealer it may cost you more in the long run it would be woth it, ta ta o'l chum

First no it shouldn't be due to the oil change unless they purposely disabled the blinkers.When you say four way flashers I am assuming you mean the emergency flashers. In which case if the blinkers are not working it could be the switch itself (on the column) or the flasher. The cheaper of the two parts will be the flasher which normally is located under the dash on the driver's side and costs roughly 10-20 dollars. Another possibility is a fuse as some vehicles will have a separate fuse for the turn signals and the emergency flashers. Very possibly there is two fuse boxes one in the engine compartment and one in the passenger compartment. The owners manual should tell you where they are located and possibly which fuse is which. If not there should be a diagram on the top of the fuse box lid.Driving through the puddle should not have caused damage to the blinker wiring as it would have also killed the emergency flashers as well. Since the emergency flashers work it is also not the bulbs.-----------------------------------------Reading the first answer reminded me of when a customer came into my parts store demanding blinker fluid as her boyfriend told her it was low and her blinkers would not work without it.It took about 20 minutes to explain the that there was no such thing as blinker fluid and that her boyfriend was playing a joke on her. Although it was hard to tell if she thought we were lying or if her boyfriend was lying.

Sounds like a short circuit. Maybe they damaged something when they were doing the oil change. You really need to take it to a mechanic, electrical problems can be hard to diagnose.

I'd make sure all your fuses are in good before you waste money and time with the dealership/mechanic. If they're all in good, you could have a bad fuse (get a fuse tester at O'Reilly's). Then call your dealership and have a pro look at it. And tell your husband that he's not allowed to go puddle-jumping anymore. That's bad for your vehicle to go through deep water.
