I have a 1995 Chevy S-10 Blazer 4x4.

I live in Arizona and A/C is DEFINATELY a necessity. But I have a slight problem with it...

Today it is 95 degrees. I turned my air on, and it blows cold and everything, but my temperature gauge skyrockets. It gets a little above 210 degrees. It doesn't go near the red but it goes over half the gauge.

Now, I was told it could be my radiator (which is all nasty and corroded on the inside) but I have no idea.

ANY SUGGESTIONS?!?!?!

(also, the air doesn't blow that hard even at the highest setting and there is a squeaking comming from under the dash. Could that just mean I need a new blower motor???)

 

If the radiator is partially clogged inside and/or plugged with dirt on the outside, it can drastically reduce it's ability to cool the engine. The additional heat being given off by the A/C condenser sounds like it is enough to overload the cooling system. I would remove the radiator and clean it thoroughly both inside & out. With the radiator out, wash the exterior of the condenser.

 

Thank you very much for your input. I'll definately have to do that and hope that helps.

Also... My air blows cold... but it doesn't blow all that haard. And my blower motor is kinda squeeking. If I replaced the blower motor would it make my air blow harder?

 

If the blower motor is squeeking, that probably means that the bearings on the motor are starting to go bad. If that is the case, the motor will not be able to obtain full RPM due to the additional drag. You can apply power and ground to the motor directly from the battery to see if it runs any faster than when the fan is on HIGH, but if it runs the same speed (as it should), then the problem is the motor. If not, there could be loose and/or corroded connections causing a voltage drop to the motor.
