Classic/Antique Car Repair: 1937 Ford

Question
Hi Brad,was wondering if you can help. Just purchased a 1937 Ford from out of state. Did these cars come with heaters? Car has wipers on outside but I see no knob or way of operating them. Thank you for any info you can provide.Tom

Answer
back in the day heaters were an option. The heaters were for the most part a dealer installed option. The wipers are vacuum operated and there should be a control valve in the vacuum line.  Some of the Ford models had the control knob above the windshield in front of the driver.
