No power to the fans 89 GTA Howdy, After years of looking I finally got myself a convertible GTA however it’s been sitting for years. I finally got the car running and had to replace the radiator as it was toast. All back together, start it up and the fans didn’t kick on. I found a broken wire harness end at the coolant switch on the passenger head so I replaced the switch as well as wire and still nothing. I jumped the relay at the piggyback at the one mounted at the radiatior and the driver’s side fan kicked on. I then grounded the wire leading to the coolant switch in the block and the passenger fan kicked on however I lost ground so when I re-grounded it this time the driver’s side fan kicked on. That’s telling me the relay is ok. Am I overlooking something? The car will shoot past 220 and nothing, even turning the ac switch in the secondary won’t even kick on. |
Re: No power to the fans 89 GTA the switch in the head is the ground unhook the harness and ground out the harness to see if the wiring is good and don"t put pipe tape on the switch it wont allow the switch to ground to the block |

Re: No power to the fans 89 GTA You shouldn't be able to actuate both fans by grounding the fan switch wire unless somebody wired them together in an attempt to solve a problem where there was improper fan function. Possibly had a bad fan switch and tried wiring them both together so the computer would turn them both on? Can only guess what some genius thought up. You need to follow the wiring backwards from each fan to each fan relay to look for weird custom work and undo it. Good luck Henry |
