I have a 1991 Chevy Cavaliel with approx 117,000 miles 2.2L, automatic. I am having a problem getting the cooling fan to work. The fan will not come on at all, not even if you turn the A/C on. I have replaced the thermostat, temp sensor, Temperature Switch, and even tried a new relay if there is only one. The only way the fan comes on is if you hardwire the fan to the battery or if you unplug the Temp sensor which causes a trouble code to default the fan to come on.
If you can help me fix it I will make a donation. I am NOT getting 12 volts at the fan, I am getting 12.4 V at the fusible link and at the relay but nothing coming out of the relay to the fan, I get 12.04 V at the temp switch but for some reason I only get 5.03 V at the coolant temp sensor. I followed the two wires for the temp sensor all the way to the big connector with all the wires that go into the inside of the car by the back firewall and I am only getting 5.03V at the temp sensor wire there as well, If you give me the answer that allows me to fix this problem I will make a donation.
have the same problem?
