My car began overheating. No noises from water pump, no coolant loss. Upper rad. hose was soft. Replaced thermostat and bled the system through the screw on the thermostat housing. No problems for a month. In fact, she ran better than in a long time.
Yesterday suddenly the temp light began blinking and the gauge suddenly went all the way up. I immediately pulled off. Within minutes the gauge was normal. Took off again and within a few miles it heated up again and this time the gauge slowly climbed. Water in reservoir was cold to the touch. No loss of coolant. Fans work. Upper rad. hose was hard. Front of rad. steaming. Heater would not work. AC was still cold.Clearly there is something stopping circulation. But where?

WHILE HOLDING THE KEY IN CRANK PSOTION NOTHING HAPPENS AT ALL UNLESS U ROCK THE VEHICLE LEFT TO RIGHT. CRANKS RIGHT UP EVERY TIME WHEN I DO THIS. CHECKED GROUNDS THEY R GOOD.
Battery dies in a few hours 1 time, might last days the next time. Replaced battery, failed load test. Replaced starter, excessive draw while cranking.Replaced radio, had a internal short causing it to stay powered up on occasion. I have isolated it to the rear fuse box under the seat by the battery.
The car has remote start so there is a brake in the wires that come from switch on the hood latch. It gives me hood open all the time therefor I can never put the alarm on. I have replaced the hood latch assy to no avail. I need to know where the 3 wires go so I can replace them. A wirering diagram would be helpful.
