castrol 20w50

and you can, but it might make your engine leak, besides its a m10, 20w50 will be fine.


&, the resistor might be bad in it.

if the blower doesnt work in any speed its probably either not getting power or the motor is bad. the resister only controls speeds 1 and 2

yes not running at all

where exactly would i check for power?

in the access pannel in the bay? or do i have to go in through the dash

Pop the hood and check the fuses. The access panel is behind the intake manifold, on the firewall. Easy to remove. Under it you'll find a blower fan and a resistor on it.
