Cooling Fan Probs 1999 Jgc

Has Anyone Ever Herd Of The Main Ecm Causing The Fan Relay Not To Function? I Have Replaced The Relay Under The Light And Have Checked The Fan It Works Fine. But It Stil Will Not Come On On Its Own At Full Opperating Temp And With The A/c On

I was convinced it was the relay, but after buying a new one and trying it the fan still wouldnt spin. Using my head, I pushed the fan and it began to spin. So, the fan only begins to spin when given a push, and does not start to spin on its own. The old relay still works.

The car constantly overheats when stopped or in slow traffic. Even with the fan spinning, the engine does not cool much. I am unsure, but the fan doesnt seem to spin very fast.

A friend has suggested it might be a temperature guage for the fan, or binding in the bearings of the fan.

Any thoughts?

If the fan needs a push to get going,its junk.If it seems like it isnt spinning fast enough,it probably isn't and that is another sign of a defective fan

Seems to be the fan then. Any suggestions on where to buy a new fan and also where to sell my new relay that was used once?

Thanks

If anyone is interested i have a new fan relay that was used once. I bought it for 75, ill take the best i can get.
