A device for controlling the room temperature of an existing automobile comprising:

• a base plate having a support shaft means at one end thereof;
• a lever rotatably supported at one end thereof on said support shaft means, said lever extending toward the other end of said base plate, and terminating in a free end;
• a temperature-responsive spiral bimetal means supported on the rotatably supported end of said lever;
• said spiral bimetal means including a spiral portion and a free end, said free end having an insulating plate attached thereto;
• an iron piece attached to said insulating plate;
• a magnet attached to said base plate in spaced opposed relation to said iron piece;
• a contact attached to said insulating plate, said contact being spaced from said free end of said bimetal means and from said iron piece;
• a mating contact attached to said base plate in spaced opposed relation to said contact on said insulating plate;
• a lead wire means for each said contact and said mating contact for connecting said device in series with a blower motor of an existing automobile;
• a knob means attached to said free end of said lever for rotating said lever and said bimetal means therewith;
• and
• a stopper means for releasably retaining said knob means at a position in which said contact and mating contact contact each other regardless of the ambient temperature acting on said spiral bimetal means.
