QuestionHi - I have a few questions for you. First, I have an 03 Discovery SE, 45,000
miles, just out of warranty.
1) I have noticed a vibration/ shuddering upon accelerating at about 30 MPH. It
seems to come from the front end, although my husband thinks it may be in the
transmission area. It doesn't happen every time I accelerate - fairly sporadic,
so far. No vibration at any other speed, or when the vehicle is slowing down.
Any ideas?
2- A/C issues... the AC/heating unit seems to be stuck on "auto" - I can still
adjust the temperature and vents, but it's always on "auto." Also, when the
system is off, a few times we've noticed the defroster blowing hot air - I have
had a LR Dealer look at the system about 6 months ago because of a "ball
dropping" sound when I turn the system off or if my speed gets above 60 MPH.
They said it's normal--- but it never made this noise before 40K miles. What do
you think the "ball drop" sound is? Is the ball jamming the system open so the
defrost blows even when the AC system is turned off?
3 - I have also had some ignition issues - occasionally the key won't turn and
the wheel is locked - seems to work eventually. LR said they couldn't duplicate
the problem. Guess a new ignition barrel is called for?
Thanks! Krista
Answer1) It's impossible to diagnose noises via the Internet but I suggest you have it checked because some noise/vibration issues can explode into costly repairs if neglected.
Front driveshaft u-joints are a particular problem area.
2) The system is on auto by design for all temperatures. Do you have an operator's manual for the system? If not, you can get one by going to www.landrovertechinfo.com and selecting "owner info" Your post does not make clear that there is any problem with your system. There is no manual mode. Did I answer that OK?
3) You probably need a new ignition lock assembly. Try graphite lock lube first, though.
