My Radiator fan is not turning on. I'm trying to find information on some troubleshooting procedures.
When my temperature gauge reaches about 1/2 way the engine overheats. It will only overheat while driving slowly (below ~45mph when the fan should be operating). Coolant is full, good condition, attempted to "burp" the system, but heard no air escape. Pulled the cap, coolant IS circulating.
I jumped the fan directly to the battery and it operates perfectly.
I'm not sure where the issue is. Please correct me at any point. I need to test the engine coolant temp sensor(Pass firewall), the fan controller(under dash near fuse box) and the IRCM/CCRM(Pass fender well).
Can someone please confirm the location and testing procedures of these parts?
I have a Fluke multimeter and jumper wire for testing and know how to use it, so you don't have to break it down completely barney-style, but if you can explain what values to look for and where that'd be fantastic.
Please teach me a lesson. I have a baby due soon and I really hate to give my money to untrustworthy shops around here
