Tempra 1.9TD Problems
1) Battery light sometimes turns on and suddenly off again
This sounds like a connection fault or the alternator brushes are worn. The
alternator has two wires (main charge and sense wire) going into it. The
main charge wire is bolt connected. The sense wire is the thin 'spade'
connected wire. These often get dirty or corroded and will cause your sort
of problem. If this connection is OK then it could be the brushes worn.
2) Resistance Light ( injector heater light?) blinks when travelling over
3) Windshield (I presume wipers as the Tempra never had a heated windscreen)
wipers sometime fail. Possible relay problem.
Set the wipers to intermittant. You should be able to locate by click sound
and feel (finger on relays) the relay that drives the motor. Locate it and
remember how to quickly locate it agian. Next time the wipers fail see if
the realy is still operating. The wiper motor has an internal switch
mechanism for parking the wipers. If these contacts or operating levers are
dirty/or faulty then the wiper will not correctly function.
The wipers in most Fiats have sliprings on the big gear
that is driven by a worm gear on the motor shaft.
The gearbox lubricant seems to be black molydenum
grease, the sliding contacts have to make electrical
contact for it to work, but the sliding action seems to
filter out the molybdenum (disulphide) so it builds
up and finally lifts the contact off the slip ring.
Result no wipers, but it generally starts working again,
for a short while, after the car has been parked overnight.
I clean the sliprings and re-lubricate with petrolium
jelly or plain lithium grease.
This seems to cure the problem.
With the wiper gearbox exposed you can usefully
-SLIGHTLY- increse the wiping contact pressure,
bending the blade slightly is better than trying to
increse the sharp creased bend, less chance of
breaking the blades.
Obviously too much pressure greater wear.
Problem seems to occur after 2-3 years, but obviously
depends on mileage and climate.
