You can jump across the celonoid on the starter. If the engine turns over then your problem is either the celonoid or the starter switch.

try taking a power wire from the battery positive and getting it on the starter terminal and seeing if the starter turns over if it does it could be a fusible link that runs between the starter terminal and the relay

SOURCE: Car died the other day, and now it wont start. Everything such as dash and radio seem to be working fine.

hi there the things to check are do you have a spark at the plugs?
do you have compression ?
are the cam shafts turning?
is the cam belt intact?
this are all needed to make the engine run it will turn over great but not start with this things not working infact if the last 3 are not there it will sound diffrent when you are turning it over with the key.

hope this helps Regards JR

SOURCE: air condition blows hot and dash reads ecm data link problem

it's your instrument cluster (digital speedometer). Changed mine today with a used one at the junk yard. A $50 fix, but it's worth it. The only way I knew was to buy the service manual for the car.

1983 olds 98, looking for blower motor relay. blower turns on when hooked to battery but doesn't turn on with heater controls.


The fuse will be marked "htr A/C".It might be on the very top row of 2 fuses or it might be in the center next to "B/U horn". There is also a resistor on the heaterbox beside the heater motor that goes bad quite often. It could also be a worn out fan switch inside the car. I would replace the resisitor first.

1991 Olds 98 Elite heater blower motor continues to run with key off. Will change speeds with controls but will NOT shut off..


if you haven't got your blower fan fixed yet, im sure it to be the same as mine, the blower motor relay which is out on the firewall under the big fuse block. take plastic cover off over the fuses and move the fuse block out of the way and you will see it staight under that. should be two screws holding it on.

Where is fan relay for heater-ac


There is a blower motor resistor that controls the speeds of the blower. It is by the blower motor and will have a group of wires. It usually has 2 small screws holding it on.

Heater fan will not run


check the heater blower motor resistor not entirely sure where it is on your vehicle but they are always located near the fan in the heater box
you may also want to check the fan speed switch as well as the heater fuse in your fuse box
Hope This Helps.Good luck
