Saturn Repair Problems? Ask a Mechanic for Answers ASAP
Hello. Can you feel the heater core hoses and see if they both feel hot? They are 2 rubber hoses, about an inch in diameter and a few inches apart from each other and go into the firewall. See if they are hot, warm, cool. Let me know what you determine.
I am wondering if the coolant is flowing through the heater core or if the heater core is plugged. If the hoses are hot when the engine is at operating temperature, then the coolant is flowing, but if not then it's probably plugged up and needs to be flushed.
The fast clicking is probably the relay. I don't have access to my software at the moment, but See which one it is, and swap it with another one and see if the heat works.
I think the rapid clicking is a relay. I would try swapping it with a different one to see if it continues to rule out a bad relay
Did you notice which relay was clicking? or if it was even a relay?
If it's a relay that's clicking rapidly, I would first swap it with another relay in the relay box.
If the heater core hoses are not hot when the engine is at operating temperature, then you would have to back flush the heater core with a garden hose to clean it out.
to back flush the heater core, I would suggest you clamp off the one inch hoses to it, disconnect the heater core and run a harden hose through it.
Under the hood, you should find the relay and fuse box on the driver side. I don't have access at the moment to my software, so I can't get you a diagram, but it's where all the fuses under the hood are located.
If they are hot then we will need to see if your getting power at the blend door actuator
Sounds good. I'll be around
I think you have a bad connection or an intermittently failing blend door actuator. Will be hard to figure out though if it's working correctly at the moment.
I have attached an image of the blend door actuator. item 6. It is accessible by removing the glove box. Next time this happens, check to see if the actuator is getting power and operating.
