:wtf:
Year / engine ,body style ( coupe or vert ) would go a long way ...........................
What area of the car????????????????
Ever considered the obvious that a PO may have cheaped out and installed a non defrost glass ????????????
Once again ; year dependent. Many years have power feeds direct from the battery terminal
Is the wiring stock appearing?
Any PO may have done wiring mods to the car in the last 20 years, removing some item they had wired in before sale
