Problem with radiator fan speed being low when sitting

Customer Question

problem with radiator fan speed being low when sitting idling after gets hot. Fan comes on normally for awhile, but when gets hot in engine compartment, fan will not activate to high speed as needed. Then It will run slowly, but will speed up when push connector toward radiator. (2010 chrysler T&C). I replaced high speed fan relay. When relay initially starts clicking, no voltage is going to fan motor connector. When fan does start, it is low speed and then speeds up when connector is pressed sideways. It reads 13.45 volts when disconnected and tested when fan is running. Is there second relay, or a bad connection in motor , or was my replacement relay defective? EM

My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

If you are able to press on the connector and the fan speed changes this usually indicates that the fault is in the connector or connection itself with it being loose,damaged or corroded needing repaired or replaced.I would inspect the connector/connection for any issues and if any issues are found they will need repaired to correct this fault here.If this is or was checked and found o.k. let me know.
