I have a 89' Convertable with 35K miles. The car sat up in a garage for 6 years before I purchased it. After two days work to get it running, it runs perfect. Everything worked except the radio and the Bosch anti-lock brakes. I found a bad wheel speed senser which was changed. Still no luck. I started changing ABS relays one at a time. I have changed two so far (part numbers 1636973 and 0-332-002-171) and still no joy. The third ABS relay (0-332-205-003) is not available from anywhere I could find. Anyone run into this Bosch Anti-lock brake problem before? Any ideas on locating the relay? Can I use a 90' relay?

I assume that you checked the fuse?

Yes. I have been sticking the DVM everywhere. It shows power in the connectors to the three relays

Assuming you already know you have to drive it a little after making changes for the ABS to reset? There should be a code, have you checked? Try Chris at 770-546-3504, he might have the relay you need. Or maybe
vette2vette.com?

Vette2vette is great source for parts and info. Used them for a few parts already, I have.:thumbsup3:

Got my $$ on this! Good luck!

What did it end up being?

Sorry for not responding. I've had a quad by-pass and several other problems. I didn't touch the C4 until this month.
I still have the ABS problem. Fuse is good. I purchased a 90' relay and installed it. So, I have changed all three relays and checked everything I could get to with a DVM, including all four wheel sensors. It checks out. I took the car to a friend that is a GM certified tech. He spent about 2 hours on it. No joy. We both are stumped. Any ideas? The car drives great and the brakes work fine, except for the ABS.

Is it a 'must' that it works? The car will brake normally without the abs working.

You can replace the abs module fairly cheaply on ebay. There are a couple guys I watch and have bought from, that are parting out a 87, 90 and 93. I've seen the unit and module listed. s10parts and karstuffs corvette.


I haven't bought from this guy, but here's the whole setup for $75, 86-89:
