If you are talking about the .5 uF caps marked 54 and 59 on the schematic, then as Terry mentioned they are definitely metal cased paper not electrolytic. These are used for interference suppression filtering.
In any case, they have no bearing on the actual reception or lack of it, other than to reduce noise from the vibrator supply and car electrical system.
If you receive no stations and only hear hum, then the problem is elsewhere
