We has our windshield replaced on our van and now the radio doesn't work. I can get a couple stations here and there, but its like there is no antenna at all. Is there a fuse for the just the antenna or something I need to check with it. Most of the stations are static until i get to the city then some work ok. But none of the AM stations work. Everything else is working fine.

Any advice on how to fix this would be great!
Thanks

 

There is no fuse for just the antenna. The cable runs from the fender to just behind the glove box. There is an inline connnection and then runs to the radio. These are antenna tests you can do with an ohm meter.

TEST 1


Test 1 determines of the antenna mast is insulated from the base. Proceed as follows:

1. Unplug the antenna coaxial cable from the radio chassis and isolate. Remove the antenna mast.
2. Connect an ohmmeter test lead to the inside center of the antenna base. Connect the other test lead to a metallic portion on the outside of the antenna base. Check for continuity.
3. There should be no continuity. If continuity is found, replace the faulty or damaged antenna base and cable assembly.

TEST 2


Test 2 checks the antenna for an open circuit as follows:

1. Unplug the antenna coaxial cable connector from the radio chassis. Remove the antenna mast. The painted mast prevents measurement directly through the mast.
2. Connect an ohmmeter test lead to the inside center of the antenna base. Connect the other test lead to the center pin of the antenna coaxial cable connector.
3. Continuity should exist (the ohmmeter should only register a fraction of an ohm). High or infinite resistance indicates damage to the base and cable assembly. Replace the faulty base and cable if required.

TEST 3


Test 3 checks the condition of the ground between the antenna base and the vehicle body as follows:

1. Connect one ohmmeter test lead to the fender on an exposed metal area (paint and e-coat must be penetrated to obtain continuity). Connect the other test lead to the outer crimp on the antenna coaxial cable connector.
2. The resistance should be less than (1) ohm.
3. If the resistance is more than (1) ohm, clean and/or tighten the antenna base to the fender mounting hardware.
