Sorry about this to the mods, but I got no reply in the Tech section of forum.
I have a problem with the thermo fans in my '96 EL (6 cylinder) and I think its my thermo relays. Problem is they dont come on till temp goes to 4/5 of 'normal' and only high speed comes on. Low speed does not work even with the aircon on.
I just had it side by side with my mums 97 EL in the garage, and the thermos in that car run fine, once it reaches running temp low speed comes on to regulate temp also if aircon is on, low speed fans are on no matter what, high speed comes on if aircon is turned up to speed 3 or more. Where in my car nothing happends the thermos are dead regardles of aircon. they only come on when temp goes up pretty high, and its high speed that comes on.
Now I compared the relays in the two cars and they are different!!
Here is that i found relays 1 to 4;
My car '96 EL GLi (stuffed): R6H3, R6H3, R6H5, no relay
Mum car '97 EL Futura (good): R6H0, R6H5, R6H0, no relay
If you have the time to look at the relays in your car or know what relays I should have can you please help!!! The thermo fan relays are infront of the air cleaner element box on the right. Thanks in advance!
