Default Heater Control

I have the electronic heater controls and the readout goes from 85 degrees to 90 degrees. The problem is that 85 degrees is too cool, and 90 is too hot when its cold out.

Is this common, and is there a good solution?

Mine is the same way, it happens on the low end with 60 being the coldest and then the next step up being 65.

I don't know what to tell you without it coming across like criticism. Everybody's internal thermostats are different. When I set my heater on 80, after a few minutes I feel like I'm on fire. I can't even imagine 85 being "too cold".

Maybe your heater isn't making the heat it should?

Seems like some type of controll valve problem. Just interested if it was a common issue and if there is a common solution.

Even my daughter complains that is is too cold or too hot. One extreme to another.

I have a similar situation on my 95.If i set the temp for 78 degrees it is very warm untill the first 15 minutes.The temp is lukewarm (almost cool)after that.If I set it on 90 or even 85 its very hot.I heard it could be the ambient temp. sensor located on passenger side under the radiator but have not had any time to check it out yet.
Good luck-let us know if you find a solution

Stick a meat thermometer in your vents to see what it's putting out.

Just an update that may be of use...

I replaced the collant temparature sensor since it was making me crazy with a bucking and cutting out problem. After I replaced the sensor, my heater control problem was solved too. Someohow the coolant sensor must have some control over the heater control.

Works for me...

Remember the T-stat is cycling open/close and that changes temp of coolant throught the heater.

To solve the control issue, try using the manual temp setting instead of auto, or auto instead of manual.

BTW, the internal air temp sensor is located under the bow, on the driver side I believe.
