Well, I just put the new engine in my 89 SC and it has been running higher than I like on the gauge. Never overheated or got above "m" in norm. I
I used to run the A/C and leave the fan on. I just switched to a 90 Processor to delete the EGR valve check engine light and fans were fine.
Now, with A/C on, fan will not come on with it. It will idle and heat up and then the fan comes on at about "m" in norm and the whole engine slows down due to current draw for the fan.
My guess is the fan is not working at low speed. Big question is can you unplug the ECT sensor and make the high speed fan come on??? Mine will not come on doing this and I thought that this was a way to test it.
I also did the code scan and got code 88---Electro-Drive fan failure----
Is this the end for the fan or is it possibly an IRCM issue. I swapped the IRCM off a 90 onto it and no go.
Could I just have a bad fan. Tried jumping the fan out and can't get it to run.
Really need help!!!!!!!
Thanks in advance........
