RE: need help asap 98 deville fans not coming on
 

car has not goten past 210 temp. i pulled out the connectors on the relays now i have a code . it has now went away but has came back not sure what code it is..

RE: need help asap 98 deville fans not coming on
 

If car has not gone over 210 why are certain there is a problem? A/C has to work for fans to come on.

RE: need help asap 98 deville fans not coming on
 

yeah either that or hit a higher temp and then they turn on. i was concerned to when i got my first lac but then after asking around all my other buddies that drove cadillac turns out 196 - 224 is a normal running temp for the N*

i just read how to check codes , i will chech them tommarrow thanks

RE: need help asap 98 deville fans not coming on
 

well the manual says 180 to 200 is the temperature, but i know it goes more than that functioning normally. I'm not sure but i think the fans go on somewhere around 216 on low and then go on heavy at around 226 somewhere, this is without the A/C on.

ok , car has hit 220 now but still no fans .i pulled codes an there is 7 codes,
po401 egr flow insufficient,
po420 catalyst system low efficiency
po463 fuel level sencor circuit high
p1660 cooling fan control circuits
b1163 loss of serrial data - no lamp responce
b1327 vehicle system voltage below 9.0 volts
u1096 loss of communication with ipc
pcm ?

every thing seams to work good on the car but the fans an the drivers window .
so u guys tell me ? do i need to start a new tread ? thanks
