Non-AC cars have a 10A fuse installed in the "heater" slot of the fuse block. The '63 and '65 AIM C-60 section indicates that with C-60 this fuse is replaced with part number 120114. The '65 owner's manual and AMA specs say this is a 30A fuse, but the '65 Shop Manual Supplement says 25A. So Joe, from your parts data can you tell us the current rating of the 120114 fuse?

Re: C-60 part number help - Joe L.
Thanks for the responses, guys. I rode with Michael G., owner of the Goldwood Yellow '65 L-76, C-60 Coupe, to Laughlin last week. (He got a Top Flight.) It was cool enough on the way over that we didn't really need the AC, and Michael was concerned because the "heater" fuse in the fuse block had blown a couple of times, which caused the AC to quit. He's owned the car for less than a year, and when the first fuse blew, which was a 10A, he replaced it with the same rating, and the "heater" receptacle in the FB is also marked "10A" We're both smart enough to know that you don't install a higher rated fuse unless you can verify it with reliable documentation and expert advice. On the way back it didn't get warm until we dropped down off Cajon Pass into the LA basin and got into some traffic, so we turned on the AC and the fuse blew after about ten minutes. Our research indicated that with C-60 the "heater" fuse in the FB should be a higher current rating, but the current rating data was conflicting. Thanks for helping us verify that it should be 30A.Comment

Duke - The 1965 CORVETTE AIM shows on UPC C60, SHEET E2 the following under Item #6 120114 FUSE INSERT IN FUSE PANEL RECEPTACLE MARKED "HEAT-AIR COND". I also checked the 1967 CORVETTE AIM UPC 60, SHEET 1 & Item # 7 reads the same & I checked the fuse in our 1967 w/C60 & it is a 30A fuse. I cannot say that the 30A fuse in our '67 is the original fuse since we bought the car in 1983 but I can say that with the AC on the fuse did not blow. PeteComment

Re: C-60 part number help - Joe L.
Interesting that the AIM calls for a 30 amp fuse; the '65 service manual puts a 20 amp fuse in the block. Which one to believe?

Michael - Interesting situation.
I checked the 1965 CHEVROLET owners guide (I don't have a 1965 CORVETTE owners guide) & it indicates "Four Seasons Air Conditioning .. SAE-30 amp" and the Corvette 1966 0WNWER'S GUIDE SHOWS in the FUSE AND CIRCUIT BRAKER DATA , Air Conditioning.................... 3AG/AGC 30 amp.
So, since the pre-1967 fuses aren't color coded if the 20 amp works, only you will know.
