    '88 CRX - gauge climbs slowly to full hot (approx. 15 seconds) after key is turned to "run" position. Engine not running, and cold, but gauge still climbs to full hot. Can pull wire off of sensor and gauge may or may not fall off to cold. Have replaced sensor with known-good unit, replaced connector, pulled wire and replaced, skipping main harness connector inside engine compartment. On occasion, gauge will appear to work properly, but is rare. Any ideas? Anyone have a schematic or wiring diagram of instrument cluster, esp. gauge section?

Car overheats and a/c starts blowing hot air when at a long stop light

It sounds like your cooling fan(s) are not working. Most vehicles run the cooling fan full time when the A/C is on so that air is always being drawn through the condenser. If the A/C is not on, then there is a coolant temperature sensor that should activate the fan(s) when the temperature reaches a specific temperature. It will cool down when the vehicle is in motion because the forward motion of the vehicle forces air through the condenser and radiator assemblies. You need to check the fans and the fan circuit for problems since they don't seem to be working in for either A/C or temp sensor.

Sounds like you have a bad thermostat that needs replacing or an air pocket in the cooling system. Does you cooling fan also come on when it's hot? If it does then it is for sure one of the two above and if the fan doesn't come on then you may need to replace it.

Temperature gage high cooling fans works sometimes coolant level normal

There are 2 cooling fans one that runs Ono and off Witt he temp of the engine and 1 that runs when you turn on the ac. The fans wiring harness can hook up opposite ways. Meaning that the fans can run backwards if it is hooked up wrong. When the fans are running they need to be pulling air inward towards the engine not blowing out through the front of the car. This is the first thing I would check if it isn't running hot but the temp is above normal!!!

your thermostat is stuck in the closed position, replace it, anytime a hose blows off, this is usually the case, remember when replacing it that the spring part of it goes towards the motor

Car runs hot. Its 2005 grand prix

Start by flushing your coolant system, then refill with a quality coolant.
Run up to temperature and check again for level (when cool again)

Check that the radiator is getting really hot quite suddenly when running from cold, as this is the best way of checking thermostat operation.
When over a set temperature (check your manual) the fan should come on.
If it never does - troubleshoot the fan (temperature switch or sensor first, then fan on direct feed to see if it powers up ok)

Temperature gauge back and forth between normal

the fan comes on and off based on the "temperature sending unit" thats a thermal switch mounted on the radiator .. it is normal for the temperature to fluxuate as the fan turns on and off .. if it is allowed to get too hot before turning on then the temperature sending unit should be replaced ...while the car is moving the fan may never come on and isnt needed as long as air is flowing through the radiator .. as long as you are not loosing coolant then the temperatures are probably within proper range ... a sticking thermostat can also cause increased temperature range fluxuations .. that will show up as large swings of temp while driving .....
