2. Disconnect the temp sender wire from the sender. Alternately short the wire to ground then remove it. You should get a full scale deflection on one of the conditions (probably shorted to ground). If this works, replace the temp sender. If it still doesn't deflect, the guage in the dash is most likely bad.
3. Brake light (turn signal) or parking light? IS the front lamp also out for the same function? If so, check F33 - 7.5A i the under-dash fuse panel. If the fault is only with that corner, the problem is in that corner whether it be the lamp socket or the wiring to it.
5. Suspect the sway bar end link and/or bushing. Inexpensive part (end link) from the dealer only). Bushing is available aftermarket from Moog. If indoubt, remove the link and see if the problem is gone. Just don't drive curves very fast as you will experience a large increase in body roll with the sway bar disconnected. Check the other side also.
