I have a 2008 DTS that is overheating due the fans not operating correctly. The fans do not come on. Only 1 fan will come on if you run the AC, the passenger side fan runs with the AC on, the driver side fan does not run at all. I replaced the entire fan assembly (2 fans in the assembly) same thing happened with the new fan. I checked the relays, they tested good, I replaced the relays just for the sake of it, fuse is an inline fuse you can view, it looks good, put a reader on it tested good, coolant levels are good, replaced thermostat for good measure. What can the issue be? why is the driver side fan not coming on, and why is the fans not running without the AC on? This is driving me crazy. -
Hi All, I haven't been on the forums for a while - life has been busy, and the DTS has been running great (around 105k miles)! Until tonight. I pulled into the driveway after a 25 minute drive home (80°F ambient temperature), windows down (A/C off), I got the message "AC off due to high engine temp" or something similar. After I turned off the car, both rad fans continued to run for a couple minutes. After dinner, I went back outside and noticed coolant under the driver's side of the car (approximately below the water pump). I plugged in my OBDLink MX and turned on the ignition to check for codes - nothing showed, and coolant temp around 160 as reported by the OBD dongle. I turned on the car and verified that the pump belt was in tact and driving (it was), the temperatures quickly rose to 220 (fans on), and I shut off the car shortly after. I'd also cranked the heat in the car but the air didn't feel hot at all. Based on the location of the coolant dripping, I initially assumed the pump was bad, but when I searched for info on failed pumps, most posts talk about a broken belt. There appears to be coolant in the surge tank but I haven't opened it yet. Do you have any advice to help me troubleshoot this issue? Thanks,
